I'll need to read that thread. So to get 1 player in we need to get rid of 2. But to get another player in, we wouldn't have to get rid of another. Doesn't quite make sense - I'll have a look at the other thread.
It depends on where they play. If we don't get Pogba/alternative we may be light in midfield so Zucculini, could be registered in the CL squad as one of the 17 free/foreign spots. But in the PL Zucculini doesn't take up a spot. I think it's the same with Kelechi. In all honesty, it confuses the fuck out of me.
