His game is diametrically opposed to how we play. He needs time on the ball, time neither Pep nor the league is willing to give. The prem is not the Italian league or a world cup where the game is not generally as good technically.
Utd have not been great but he has been a large part of their issues, he has not stood up to be counted at all. This fallacy he has only been crap at utd because they are is disingenuous in the extreme. They have not been so bad that it stops him putting a shift in more than half the time. Nor should it make someone dash of for holi... for physical recovery therapy the second they feel a twinge.
Ragnick himself said he put a stop to this "recovery" in Dubai nonsense as they have perfectly qualified medical staff and equiptment in the UK. He stopped it because players doing it were taking the fucking piss.
It speaks greatly of a persons fabric and anyone aiming to dismiss that is not being objective or reasoned. Grit and determination are equally as part of any good or great players fabric as technical ability. Look at Dave, technically the best i have ever seen and tenacious as a dog digging for a bone.
