What are the realistic options for Cancelo though, at any price? He'll want to play for a Champions League club, he doesn't want to stay in England, Bayern aren't interested, nobody in Italy can afford him, Real don't deal with Mendes. That leaves PSG, Barcelona, Atletico Madrid.
He's the opposite of a Simeone player, so rule Atletico out. PSG may want to cover their bases at full back with Hakimi's rape case hanging over him. Barcelona have wanted him for years but can't afford, or don't want, to pay for him.
The other factor is that unlike Laporte and Bernardo, keeping Cancelo is the opposite of desirable. We need shut of him and other clubs know it.
I just can't see any other scenario but a loan to PSG or Barca late in the window - and unless he performs exceptionally wherever he goes, we'll likely be loaning him out until his contract runs down.
