Certain bit of arrogance is a pre-requisite to manage a club like ours. He's never been averse to changing it around when it doesnt work so that's a relief. Also, just like anyone here, he himself acknowledges that the team will be better going forward if we play the diamond but believes our defence isnt good enough to cope with it.
As I see it, this season he's focusing on results more than performances and in the summer, he'l buy defenders and go back to 4 in the back. It isnt great to watch but as long as it wins us games and gets us the top 4 spot, I wont complain. Mourinho did it last season too, got results while not being great to watch and after a summer where he got the players he wanted, they're tearing teams apart. Unless people here believe LVG is some shit manager, I dont understand all the uproar. This season is about getting back to the top 4. If the manager believes the defence needs an extra man to cover for lack of quality, so be it.
My biggest gripe with him is playing players out of position. Rooney and Di Maria should be playing in each others positions and we'l instantly look a better team.
EDIT: Just to be clear, I'd rather we play the diamond too as I believe we're good enough to win playing that as our improvement in attack will compensate for the weakness in defence but if the manager thinks it wont and we need to play 3 at the back, I'l complain from time to time but will accept it as long as our goals for the season are met and we buy the players to set things right in the summer.
