His record is the same, as a winger and as a CM. The only difference is that people began to see his brilliance as he was moved from that dreaded right wing which is supremely unbalanced with the inclusion of Ronaldo on the other side and the fact that the technically poor Khedira removed from the team altogether.
Place Di Maria in a formation that is not lop sided and when the defensive duties do not drown him, his brilliance will come through in offense. When Bale played on that right position, he was pants, utter pants. No one, besides him, and perhaps Ribery, can do the defensive and offensive work that Di Maria. Isco did a better job for us defensively when he "sacrificed" himself for the team than Bale in the Champions League but he disappeared up front more or less.
For Real Madrid, I am glad an energetic Kroos in midfield who is more mobile than Xabi and more technically gifted than Khedira came because it softens the Di Maria departure as he balances the team. Di Maria balanced the team with his "omnipresence". If we had kept Khedira (technically poor), and Xabi (not mobile enough) and let Modric do all the work, we would have been destroyed without Di Maria.
Manchester United moves in lines, and more uniform so it helps Di Maria shine. Provided they know learn how to pass the ball and defend, lol. At Real Madrid Di Maria was himself running between the lines, carrying the ball up front and running back off it.
