The biggest thing with Keane for me is, he’s relentless for holding grudges, and he’s very knee jerk.
I feel like a player would only have to make one mistake under him to be scrutinised indefinitely by him. That’s a double edged sword, because those players who are underperforming often need an arm around them and a bit of reassurance, which I don’t think Keane is capable of.
And on the other hand, those players who do 90% of their game well, being criticised for one minor flaw or mistake is going to create friction between the player and management.
Keane’s personality would be perfectly fine if as others have said, he wasn’t so one dimensional.
It’s about that balance of knowing when to lay it on thick with players and when to motivate/boost their confidence. For me, being patient with players during a bad run of form goes against what Keane is about as a person and ultimately as a manager.
Also, Keane seems to be unable to wrap his head around the fact that for better or worse, the changing room culture in Football has changed drastically since he was playing. The example he’s been used to of Ferguson being the manager and no one player being more important than him isn’t a thing in modern day Football, the power is well and truly with the players and until the manager can build the trust of that group, he is ultimately at their mercy.
