Need to really get this one over the line. If I were Perez though, I'd put this on the backburner and allow United to stew while the Ronaldo drama plays out. The longer it goes, the more desperate we will get - as there's no comparable striker (to Morata) available and Flo knows he doesn't mind keeping him or flogging him to Chelsea or PSG either. Ronaldo won't move. That's certain. Anyone thinking otherwise is just setting himself up for another bout of misery.
Frankly, at this time, it's probably in our best interests to give up the last 4-5 Mn and just get the deal done. If, (massive, mighty IF) Ronaldo's move is a serious likelihood, we should see it as another move altogether. We need a central striker and Ronaldo won't play that position. Morata is our best option.
