10+ then?
Had a look back and in a lot of them he was taken off way before the end, either at half time or with about 30 mins remaining. There is a reason for that, and it's because he wasn't impacting the game enough.
I hope he can turn it around don't get me wrong, I just don't think he is suited to this league based on what I have seen so far. Given his scoring record and what he's achieved in his career so far at a club as big as Ajax, there is clearly a good player in there but not all players are suited to this league.
If he puts a run together from now to the end of the season and proves me wrong, then I will happily admit I wrote him off him too early.
