No, that's bollocks, I'm happy to acknowledge the positives as well but I give it as I see it whether you like it or not.
I'm not sure that fans clinging to us having the best record since January is a solid argument for saying that Silva has individually been playing well for us. We stabilised after a very bad November and December, but the standard of performance was still some way off what it needed to be. Liverpool took their foot off the gas after clinching the league title and Arsenal put all their eggs in the CL basket. Both of these things played a part in us having the best record over that time period. We proved incapable of getting results in the biggest games - Real Madrid away, Liverpool at home, Arsenal away, Forest away, Palace at Wembley, etc. How much of this is attributable solely to Silva's performances is difficult to determine but it's largely irrelevant. My view is that he's a shadow of the player he once was and there was just as much a case for retaining KDB.
For what it's worth, I think Khusanov is a magnificent centre-half who had a big impact in helping us to stabilise before mysteriously losing his place in the side. Gvardiol moving to central defence and the emergence of O'Reilly also helped massively in propelling us towards CL football. So there goes your wanky argument about only seeing negatives in players.
