I just don't understand you sometimes.
You give it big over Stones, Lukaku etc including defending them against those that look at their inefficiencies yet you won't do it for Keane.
How many times did Stones show positionally he was gunk? Even Paul Merson saw it.
It's what happens when players are adjusting / going throw issues of confidence.
Keane may be 24 but he's been hand-held for years at Burnley. He's been capped by England. Sean Dyche is a very good defensive coach - look what he's done with Burnley - and he raves about him.
This is the first time Keane is playing in a team with expansive full backs, an ever-changing CM and CB partner... and he's been here 6 months.
Is it any wonder he's being inconsistent?
But despite all this context, and despite you looking slightly hypocritical (see Stones defences above), he's a dud?
