Whether Reus decided to join us or not is a different matter, but the point is that we can afford players such as him with the sale of Pogba and some dead wood players. I'm not really sure how this is delusional.
Ok, let's say we sell Pogba for 50M (Anything lower would really be criminally insane) and we sell the likes of Vucinic for a combined 20M. There's 70M.
Plus, we obviously have some sort of Summer budget at around 20M. There's a total of 90M. Now people just ignore all of the realistic steps in getting the 90M and focus on the number then talk about it being unrealistic. There's 3 very realistic steps in order to get that sort of money.
On the Mata case, well yeah if we or any other club were trying to buy Mata 2 years ago then we would have had to put up 40M + to even get a conversation with Chelsea. But prices aren't just determined by players ability. Right now, Mata is in a bad situation and his own coach doesn't even want him. So his price is naturally going to be lower than it would if his situation was entirely different.
Out:
Giovinco
Vucinic
PDC
Padoin
One CB (Should we switch to a back 4)
Pogba - unfortunately
IN:
2 quality wingers, 1/2 cheap back up wingers
1 reasonably good CM, for depth purposes
1 left back.
Optional:
Some very cheap signings which would help us maintain our squad depth, without costing much at all.
