Pekhart has had a pretty good pre season too, we still have Aravidis, and if really necessary Bakasetas can step up and play as a striker, so do we really need another striker right now? I wouldn't prioritize it personally.
Assuming we sign Belkaroui we are set back there. A center midfielder is a must get, hopefully it's someone tall that can make us an even bigger threat for set pieces. Imagine having 5 players in on set pieces that are over 6'3, we'd dominate.
We don't want Cordero back because he's way too injury prone, and he had caused some locker room issues this past season I heard.
