Man Utd are actually playing well, though.
Their build up play is good, they are dominating possession and are attacking.
Utd played dire football, passing it around 3-4 players mostly 10 yards infront of Everton's midfield, doing nothing. Rooney has been completely rubbish, taking ages to make a poor pass which gets intercepted or is to someone offside. Even when Everton make a mistake and Utd actually try and break on them, they screw it up, Rooney delaying a pass to Nani so he was offside. One of the reasons Utd looked better was because they moved Rooney out of that play maker position. But today Rooney has either dropped a bit deep trying to find the ball and make that pass, or got the ball in the box and rather than shoot, he's pulling back and again trying to make the pass, and his passing in the final third has been abysmal. Utd looked so much more dangerous because it was Kagawa and Mata making those passes in to Rooney, Welbeck or whoever is making the run. Rooney is a very poor making those passes so I'm not sure why Rooney is attempting to do that when he's playing as the striker.
Neville is calling it right, it's utterly useless possession. They had what 68% possession at one point but it was 7 shots by everton vs 1 for Utd.
There are two fundamental reasons to try possession football, to build chance or to simply hold the ball so your opposition can't. Utd both utterly and dismally failed to prevent Everton having chances and weren't creating any of their own. Possession without creating chances and without denying your opposition chances is nothing.
If they had that possession AND Everton were limited to 1 or 2 shots that would be "good" football, but their passing was lazy. Everton stole the ball ridiculously easily ridiculously often. They were the first to every slightly loose ball or pass.
Everton by some distance the better team in the first half.
