One thing that isn't mentioned enough: The importance of QPR staying in the PL. Every game day for them is also important for us. If they stay in the league they most certainly will buy Isla for freaking 11m, if they get relegated they most certainly won't. Whether they stay in the league or not could have great influence over our doing in the summer.
Also i wouldn't be surprised if we find some sort of deal with Sassuolo that will give us both Berardi and Zaza, but will include us paying one of the 15m fee's a year later, so we have more financial room to intervene this summer. Sassuolo has a rich owner and a great relationship with our management, there is room for negotiation.
