Because Bernardo and Mahrez are not the game changers and match winners you claim Grealish is.
Sterling has over 100 goals for us, playung at the top level. It is pointless comparing him to Grealish as Grealush does not even compare.
You say he stands out in every game yet he was totally anonymous in 3 games against us last season. In the Cup Final, the game where it really mattered he did absolutely nothing and was out shone by Foden.
You are right, lets leave it here. Hes a good player but absolutely nowhere near the top top class (Silva, Gerrard, Lampard)
