He might not be good enough, but he's not the worse part of this team, and he's actually had some phenomenal performances this season. If we were at the top, then we would definitely need to upgrade but we're no way near it so he's rhe least of our (many) problems.
As for the mistake, it was a bad one, but he mishit a fucking ball. Christ, I've had a surgeon mistime a sodding cut, imagine how they might perform next time they're in theatre if they had 1000s of people booing them. The booing comes from a wider malaise, and that malaise is largely understandable however that doesn't mean it's productive because it's absolutely not. Booing a player is never going to help them or the team, it's just not. And at least he came on tv and said they had every right to boo - people expecting a greater apology here are missing the point, he could have talked about how much rhe booing hurt or how it didn't help but he took it on the chin. He didn't need to do that.
