Or he knows what to do but he doesn't currently have the players to carry out his instructions consistently enough.
You must be joking. I never played up to the level of the players that United have but any decent player who plays professionally would be able to at least try what they practiced on the training ground. They may not be able to pull it off against better opposition who are quicker and stronger and have better ball control.
But United is not playing against Ronaldo or Messi. They are playing against players like Josh King etc.
Furthermore, at a corner kick there is no opposition for them to stop them taking a kick. No the only reason why we are so crap is because he has no idea how to coach a football team. If he has he should know to get at least the set pieces right. We may not score but at least it should be worked right.
This is not a Sunday football team but a team of International football players who some of the them have played in the World Cup. Some of them in the semi finals and one in the Finals and won the darn thing.
You get the best way to get the best out of the team you have. It is no point trying to play tiki take with players like Young, Fred and Lingard et. But you can get them to play much more effectively than they are playing now. He did not realise that our problems start from the top. It still does. If the forwards cannot hold the ball then the midfield and in turn the defence would be put under pressure. I have never seen any United side that is so poor in holding up the ball. Since Zlatan left we never had the ability to do it.
Ole should not have bought Maguire. He should have got a striker who can hold the ball and who has a good touch and then a very good midfield player to replace Matic. Then only should he have looked a CB if finance was a problem.
