There might be some merit in staying at Horsens next season. He seemed to play without confidence and was quite peripheral at times - though being a small, tricky winger in a relegation side that might not be too surprising. He also has a contract until 2027 or so, and given he joined a side expected to go back down he probably doesn't have much of a relegation escape clause, so he might as well stay and fight to get them back for the 2024/25 Superliga.
In the 1. Division Horsens (I'd expect) will be one the strongest and he'll get more of a go at showcasing what he can really do. He got seven league goals last term and none this time from 0.94 xG; he only had two shots on target all season, worth a combined 0.04 xGOT, ie they were both basically as comfortable a save as one could expect. He also got two assists from 2.17 xA, so only slightly hard done by his teammates there as well.
Liam Jordan could also act as cautionary tale for Just about heading across the Øresund bridge to Sweden, as he left Helsingør after also scoring seven goals this season (not even a whole season) to promoted Brommapojkarna and has only played 23 minutes in Allsvenskan this season. BP have played eleven games and Jordan has only played twice, been an unused sub in seven and missed two.
On the other hand, AaB should probably blitz the league next year, given the size of the club and the quality they have, though they could of course lose a few players. So that means Horsens could be fighting with the likes of SønderjyskE, Helsingør and Vendsyssel for one promotion spot.
Also have to shoutout Lyngby, they looked dead and buried and cashed in on key players in January when they still had some value, and somehow managed to survive. They set a Superliga record of the biggest comeback; they were 16 points off safety after 16 rounds and got upon the final day.
