Wtf are you saying?
He was first choice centre back when fit for every manager until Ole came.
SAF - 3 years - never established himself.
Moyes - 1 year - squad player.
LVG - Year 1 - dropped after 2 games and needed injuries to get back in. Year 2 - became a proper starter when Blind moved to CB.
Mourinho - 2 years. Year 1 - Bailly signed to replace him, dropped until Bailly got injured. Year 2 - Lindelof signed to replace him, dropped until Bailly got injured.
Ole - 2 years - Year 1 - got injured as Ole arrived. Year 2 - moved on.
He was first choice
because he was fit. Nothing more than that.
31 league titles and 5 European Cups between that lot. Maybe, just maybe, they know a bit more about what makes a good defender than you?
Anyway, no point going down this road with his fanclub. He's off soon and this chapter in our history can be closed for good.
