This a thousand times, and it's reflective in our poor record of coming back and winning games under LVG. People like Fletcher, Park, Evra, Rooney(of old) O'Shea, Rafael, these players would run themselves into the ground for us.
We could point fingers at the players for lacking desire but at the same time Louis van Gaal as a manager should be able to get these players to bust a gut for him and they're not, which tells me they don't respect him enough or don't even like him.
People always say players should give 100% regardless but they're not robots, that's not how it works, they work on emotion, the amount of effort they put in can be influenced by many things, one of those is a manager and as far as this bunch are concerned, there's absolutely nothing going on.
