I'm just going to say it - I blame Pep for that.
Play the guy 3 times in 3 months, drop him for an 19 year old and then throw him back in the team on a whim in the cup final. His treatment of Stones is bizarre to me. Drops him for months, gives him one or two games then drops him again, all while persisting with Otamendi who makes just as many errors.
If his head isn't right, don't bloody play him in a final!
I feel for him. He misread it and got his legs in a tangle. It could happen to anyone but of course it's him.
That said, we got incredibly lucky for our second so i'm not that annoyed. Just frustrated for him.
