The short answerTure Spendler, Norrby's 23-year-old left-back, ranks first of 63 Superettan full-backs for progressive and long passes, and has improved in each of the last three seasons. Full-backs who stepped up from the Superettan to the Allsvenskan kept a median 94% of their progressive passing. His level: an Allsvenskan starter.
Of the 63 full-backs who have played 270 or more minutes in Sweden's Superettan this season, the one who moves the ball forward most is Norrby's left-back. Ture Spendler makes 11.5 progressive passes per 90 minutes, against a full-back median of 6.7. He also makes 10.4 long passes per 90, three times the median. He's first in the league's full-back pool for both. That isn't new. And when Superettan full-backs have stepped up to the Allsvenskan, this is the part of the game that has mostly come with them.
That's the case in one paragraph. Spendler is 23, and his numbers have got better in each of the last three seasons, the last of those a division higher. The players who have already made the jump he would make next suggest he would arrive in the Allsvenskan with his main strength largely intact. Our view is that he is a top-flight starter in waiting.
This is a Step Up piece. Each week we take one player from a lower league and ask a single question: what level is he really playing at, and what's the evidence he could do it one level higher? We first picked out Spendler in our list of eight players nobody is watching, as the safest bet on that list that his season was real. Here's the full case.
Three seasons, three steps up
Spendler arrived at Norrby from fourth-tier Räppe before the 2024 season, after coming through the academy at Öster. His first year was in the third tier, Ettan, and it was useful rather than special: 2,267 league minutes, good at long passing (the 85th percentile among Ettan full-backs), mid-table at progressive passing (the 67th), and well below average without the ball. He was in the 24th percentile for successful defensive actions and the 15th for interceptions.
In 2025, still in Ettan, he jumped. Over 2,502 minutes his progressive passing rose to the 95th percentile, his defensive actions to the 66th and his interceptions to the 74th. Norrby went up.
A step up a division is normally where a lower-league season gets found out. Spendler's numbers went up again. In the 2026 Superettan, against a pool of 63 full-backs, he is first for progressive passes and long passes, third for passes into the final third and third for successful defensive actions, which puts him in the 95th percentile. His interceptions are in the 85th. He has played 2,605 league minutes across 27 games, and public match logs show him starting every league game this season.
That's the answer to the spike-or-steady question, and it isn't close. The passing has been strong for three years and elite for two. The defending started poor and has climbed every season, in a better league each time it mattered: from the 24th percentile to the 66th to the 95th. A spike looks like one good season. This looks like a player who keeps getting better.
Over 2,502 minutes his progressive passing rose to the 95th percentile, his defensive actions to the 66th and his interceptions to the 74th.
Is it him, or is it Norrby?
There's an obvious objection. On our style measures, Norrby are one of the most direct teams in the Superettan, with a long-ball share two standard deviations above the league norm. A left-back in a team that goes long will make a lot of long passes. So how much of Spendler's profile is just the system?
Look at the other side of the pitch. Norrby's two main right-backs this season, in the same team and the same system, average about 6.2 progressive passes per 90 each. That's roughly the league median, and about half of Spendler's 11.5. The team's style explains some of the long balls. It doesn't explain why the left-back makes nearly twice as many forward passes as the right-backs. Long passes make up 23% of everything he plays, the highest share of any Superettan full-back, so he is the team's main outlet from the back.
It also tells you what he is and isn't. Spendler moves the ball by passing it, not by running with it. He's in the 15th percentile for progressive runs and the 18th for dribbles. His accuracy on progressive passes is mid-table, in the 47th percentile, so the volume comes with risk. This isn't a winger who has been moved back. He's a deep-lying passer who has been given the left touchline.
The step-up test
The next level for a Superettan full-back is the Allsvenskan, and the gap is real. On our ratings, the average Allsvenskan club is about 210 points stronger than the average Superettan club. At roughly 180 points a goal, that's more than a goal a game. Norrby, rated 988, are 12th in the Superettan.
So we went looking for players who have already made the move. Since 2023 there have been 15 cases of a Superettan full-back playing 900 or more league minutes and then playing 900 or more as a full-back in the Allsvenskan the next season. Some went up with their clubs and some moved to bigger ones. We compared their progressive passing either side of the move.
The pattern is clearer than you might expect. The median full-back kept 94% of his progressive passing after stepping up. Eight of the 15 kept 90% or more, and a quarter kept less than 79%. Defending didn't fall at all: the median mover made 6% more successful defensive actions per 90 in the Allsvenskan, which fits a full-back spending more of his time without the ball. The cases most like Spendler's are even more encouraging. Five movers arrived with 10 or more progressive passes per 90, and three of the five kept at least 98% of it. Spendler's 11.5 is higher than any of the 15 managed before they moved.
Now apply that to him. If he keeps the median share, he'd make about 10.8 progressive passes per 90 in the Allsvenskan. That would rank 4th of the 51 Allsvenskan full-backs with 270 or more minutes this season. If he has a harder landing and keeps only the lower-quartile share, it's about 9.1, which would still rank 15th, in the top third of the league.
The blunter version of the test is to drop his raw 2026 numbers straight into this season's Allsvenskan pool. They would rank in the 94th percentile for progressive passes, the 100th for long passes and the 94th for defensive actions. Those raw numbers won't survive the move unchanged. Better opponents press harder and give a left-back less time to pick out a long pass. But the movers tell you how much usually survives. For this skill, it's most of it.
The one number that doesn't travel as well is his duels. He wins 60% of his defensive duels, the 83rd percentile in the Superettan. Placed raw in the Allsvenskan pool, that falls to the 57th, about average. Wingers in the top flight are quicker and better, and his one-on-one defending is the part of his game an Allsvenskan coach would test first.
The level, and the fit
Put it together and the level is clear: a starting left-back in the Allsvenskan, at a mid-table club, with his passing as the reason to sign him. That's one division up. It isn't a leap to a top-five league, and nothing here argues for one yet.
The type of club matters as much as the league. A patient, short-passing side would ask him to do the thing he does least, carrying the ball. A side that wants its full-backs to switch play and find runners early would get the most out of him. Two Allsvenskan clubs fit that on our style measures. These are our suggestions based on fit and level, not clubs reported to be interested.
Brommapojkarna (1205, 11th in the Allsvenskan on our ratings). They're one of the league's most direct sides, A left-back who already plays a quarter of his passes long would fit how they want to attack, though his long-pass accuracy, mid-table in the Superettan, is something they would want to see improve.
Mjällby (1198, 12th). One of the most active defensive teams in the league on possession-adjusted interceptions. A full-back whose defensive actions and interceptions have climbed every season would suit a side that wants to win the ball back early.
Swedish press reported interest in him from an Allsvenskan club and from Norway's Sandefjord before this season. In the summer, a supposed approach from abroad turned out to be a scam, which Norrby reported to the police. He's still at Norrby, on a contract that runs to the end of 2027.
Our verdict
Step-up level: Allsvenskan starter. Spendler is the most productive forward passer among Superettan full-backs. He has improved in each of three seasons, including the one in which he went up a division. The full-backs who made this exact jump before him mostly kept their forward passing, so the evidence says his would travel too. His one-on-one defending is the part to watch: he wins his duels at this level, but on raw numbers he'd be only average at the next. Watch two things over his next ten games. Does his progressive passing stay above ten per 90 against the Superettan's better sides? And do his defensive duels hold up against the league's best wingers? If both do, he's ready.
