You’re misquoting Pep mate.
What he said was that Kyle wasn’t right for the stepping into midfield role that Stones can play, so not the man for one particular tactical set up.
He also emphasised that other players couldn’t do what Kyle can do.
So the Pep message was that Kyle not playing was due to the tactics employed but that Kyle was the best we have for other tactical set ups.
You have noted that other players get dropped for tactical reasons (Bernardo, Mahrez, Foden or others etc. at various junctures) but that doesn’t make them either shite or excess to requirements does it?
Not having a pop at you Willip (you’re due your view - it’s a forum innit) but I must say that I’m baffled by those posters so keen to slag off a player who has been a magnificent servant to this club, a player who remains the best we have for many set ups and who only sits on the bench due to a current tactical ploy that may not be employed against all opponents for obvious reasons.
