No, there's a section of City fans who are dug in on their opinion that Savinho is not good enough. When the lad makes a mistake the fans are much harsher with him than any other player.
This is nothing new, City fans have always loved a scapegoat to take their frustrations out on, Mahrez got this for years and ended up winning the fans over eventually.
The problem for them is that this player is hugely talented, just a matter of time before he puts it all together, and when he does they're going to look very silly.
The smart ones have already started rowing back, so kudos to them.
