I don't know to be perfectly honest, I don't get much time to watch lots of football anymore. I do know that every player we have been linked to doesn't meet my criteria in one way or another.
My dream probably would be Umtiti, it's really risky because of his injuries but he ticks all the boxes to mentor Saliba, 26, left footed, French, decent experience and undeniably World class when fit.
Elvedi is a great shout, I will have to get on YouTube and investigate hime further.
Edit - I just watched a YouTube video of Elvedi, 7 1/2 minutes and not one single last ditch sliding tackle which is a great sign. As well as not going to ground he looks very focused and composed too, I'm impressed.
The dream would be if Barca decided to let Umtiti go relatively cheaply and he comes here, gets back to his best and puts his injury problems behind him. But how likely is that to happen? Not very, probably.
