Why will we need a replacement. Redmond and Bennett are more than capable of rising to our needs. Maybe not as technically capable but much more pace to unnerve defenders, and still not the finished article. Buying a new player will just stunt their development.
Depth of the squad or perhaps you didn't notice the problems last season where the squad was in quite a bit of trouble with injuries. Also if we sold and didn't replace him in the same role or an ACM it only takes a couple of injuries and you're in big trouble immediately.
You put Bennett forward and that's fine he's a good player but what if his injury from this season reoccurs and it takes him out for 90% of next season, then you're down to just Redmond, if he's ill or injured or suspended......
It's not just about having top notch players we still need some good quality depth in the squad in those areas, selling one and not replacing would be one hell of a huge gamble IMHO
Ever since all the Toivonen 'bad boy' rumours at the start of last season. I still maintain that not signing a decent ACM cost us our place in the top flight, as there's plenty of evidence that both Hooper and RvW can score goals given the correct service.
