Obviously he should be supported up to the point where they get rid of him, if it comes to that but it doesn't mean he should be devoid of criticism. 80 crosses in 1 game yielding 2 goals, 1 of which was very lucky. How can a manager leading the biggest club in the world not change something? Throwing Adnan and Chicha was a desperate ploy in the hope that someone bundles the ball over the line.
Moyes has got more in his locker, much more but he's just not doing it at the minute. He's doing things he rarely did at Everton, like throwing in 6 forwards in the hope one of them does something. Much of it, in my opinion, is down to the media, fans and pundits pressuring him into playing attacking football and claiming he's too defensive minded. If this is the case, it begs the question of whether his mentality is strong enough to be managing a top team with the highest of expectations.
