We need more quality in final third, Yildiz will be hot and cold for a while we need a chico on the other side and eventually they all will be competing for starting spots, gonzalez depth and Yildiz himself filling in at times as vice vlahovic.
Imo wing options more pressing at this time with koop back he will take the load off, double pivot our options are fine we can think about a midfielder once we completely have given up luiz and monitor thurams development. Same for defence assuming bremer will be back and kalulu signed permanently some depth options would do moving Danilo on.
bremer's season is over, danilo is all but finished (someone really should tell motta), we can't not sign a cb in january. since bremer is out, we conceded like 5 penalties and a few red cards, and while chico's red was ridiculous and some penalties were soft, it's clear that we lost some of the defensive solidity
you're right about yildiz but if weah and mbamgula can replace him for a half or a complete game, then it's all good. nico and chico are more than enough quality on the right. dusan though, he can't play 50 matches until july, let alone 50 matches at a high level. he badly needs a backup
