I'm not claiming that Giggs is tactically better than Moyes or that either of them are better than LVG, what I'm saying is it's impossible for any manager to impose "his" style on this team which has no pace/physicality without going into the transfer market and buying it because we don't have any. Even under the last 2 seasons with SAF the performances were very underwhelming but his ability to get the best out of those players kept us as the most consistent team in the league which was enough to win the title. We no longer have SAF and those large holes in the side which most of us had identified long ago have now been blown wide open now that he's gone.
Welbeck has pace but it's never going to be utilised unless he's playing up front, he can't cross or beat a man so he's a waste in the wide areas. Valencia has pace but when does he ever make runs beyond the last defender or beat full backs 1v1? He doesn't, he hangs out by the touchline get's the ball into feet and works from there, it's fairly easy to defend against and teams have worked it out. Adnan is the type we need but at the moment he's too inconsistent to be relied on. Herrera is the type we're looking for and Shaw add's plenty, I'm delighted with those two signings but at the moment everything beyond that is speculation. Vidal is my number 1 choice for a signing this summer but I don't agree it's clear we're in for him or anyone else like him, I wouldn't be surprised if LVG is happy to stick with Carrick this season and then move for Strootman in January/Summer when he's back from injury.
Our average defender age may be young but that's not a good thing when none of Smalling/Jones/Evans have been able to complete an entire season injury free, we've been forced into playing Carrick/Fletcher as CB in the past few seasons due to the amount of injuries in that position, another CB is essential more so than CM.
Robben does not play as a second striker through the middle, he's always in the wide areas but he will periodically shift from left to right. Here's a picture which shows the positions he's received the ball in his last 3 games:
I could load up a graph from every game he's played this tournament and they'll show the same thing. In no way does he play through the middle.
