Can we put to bed the myth that Valencia is a defensive liability? Been played there by SAF (at times), Moyes, Van Gaal and now Mourinho. Last season we had the best defence in the league, partly to do with our unadventurous style, but nonetheless, you don't do that with a defensive liability as part of the unit. Moreno, now that's a defensive liability.
No, Valencia isn't the best reader of the game; but his reading of it is adequate enough. He makes up for this by being fast, strong, excellent getting forward, and very good defending one on ones. You rarely see players blowing by Tony V. He'll have bad games, everyone does. But I've always rated him highly. I love our full back combo right now. If we brought someone else in, I'd like it to be someone who offers the similar type of strong running that makes space for Mata/Micki/Lingard on the right. Fabinho makes sense because he is young and could start as an understudy.
Darmian for my money just isn't Utd material. But I'm ready to be proved wrong. He's a real steady eddie, but without any standout qualities; and once the confidence has gone, he's a pretty weak option. The player he reminds me most of, from our past, is Phil Neville; but he's yet to perform as well as Phil ever did. I just appreciate his defensive flexibility to play anywhere across the back line, and look kinda gormless while doing it.
