We'll probably end up with none of them. but Belhanda isn't really a winger, a CAM really but can play on the wing or deeper in midfield.
For arguments sake, though, lets assume all of these bids/rumours are true. We could line up:
Guzan
Lowton Vlaar Okore Cresswell
Westwood Sylla
Popov Belhanda Tonev
Benteke
But yeah, you are right. Extremely unlikely we'd sign them all. Probably 1 out of the 3, using the other 2 to keep the price of the 1 we will sign down. a la bidding for Dempsey knowing full well we wouldnt get him but closing the Benteke sale.
Such a good team. Realistically, might only cost around 30m to put together.
If we could sell Bent for a tidy sum, its not out of the question.
Can't see Belhanda joining though.
