I don't think he will make it under Mourinho, a manager who demands that every player participate in defending.
I've only heard good about Memphis attitude in training, but on the pitch it's a very different case.
Memphis should learn from Lingard, the difference in Work rate between them is night and day.
He didnt really do that earlier in the season, helping with defending. But then again even if he tried, he got called out by our fans for it not being good enough.
But in his more recent matches, he has been tracking back a lot more, our match vs Arsenal at home being the best example, he didnt do an awful lot offensively but kept one of the best attacking fullbacks of the league, out of the game (Bellerin) with good work ethic. I dont think that is neccesarily his biggest problem at the moment, him not having acclamatised to the speed of the league is.
In the PL for example, when he does beat a defender, you need to make the next step immediately, either you cross it, pass it, go for a solo or whatever, you have to have the technique to execute that extremely fast, and do it well as well. Memphis coming from the Eredivisie, when you beat a defender there, you have all the time in the world to decide what you are going to do, you dont get a 2nd and 3rd defender straight after you bwat the first one, it's a huge difference which Blind and Depay have mentioned themselves. Some players adapt to this easily, some dont. Memphis know nowa about this, and we should hope that he handles this better next season.
Furthermore, even though some expect that of him, he isnt a Hazard, Costa, Ribery type of winger. It isnt about the dribbling, skillfullness, creativity, trickery, being unpredictable with Memphis, he isnt really a winger of the old mold, he is more of a wide forward. He's strong, fast (he did look slow this season after he gained weight/muscle), has a good shot on him (hasnt really showed that this season unfortunately), has effective dribbling, flicks, touches, skills (backheels, drop of shoulder, heel flicks and those kind of things) and has a really good eye for making runs. His runs behind the defence have been good for most of the season, but we barely have players who play those passes with Mata being a coward in possession mostly, and Schneiderlin, Schweinsteiger, Herrera not really having that ability, something he was quite used to with PSV. What Im trying to say is that our rather slow paced, static play doesnt suit his play as well, he played counter attacking, dynamic, opportunistic and reactive football with PSV, which is basically the opposite of our football. Next season, hopefully under Mourinho, with new midfielders like Sanches, Gomes and a more faster style of play, him being more used to the league, I hope that he can flourish. If he doesnt, we cut our losses and both parties move on.
P.S, Im not trying to make excuses for him, he's been really poor at times and some of his performances have been inexcusable.
