CB who won 0 aerial duels in last night's game says it pretty much all. I think anyone who wandered in our box could won at least few. You can't expect good defending from anyone in your team against team that is great at set pieces when you have CB who can't win single aerial battle. But somehow, some say Smalling was equally bad as him, despite Blind being directly involved in all three goals.
Saying that, I like Blind, he is one of my favourite players in the squad, and I think he should almost always have the place in the team but not neccesarily at CB. He's had a good season overall, better than I expected, but he's had few of performances like last night when you question his ability to even play at this level. What always surprises me is his lack of position awereness, I always think of him as one of our most intelligent players only for him to do few incredibly stupid things even Rojo would be proud off. He did it in midfield too last season at times, it's really weird how his positioning can be terrible for a player who in general shows that he has brains unlike our many other players. If you count top10 worst performances from our players this season, Blind would probably have at least 3 of his there, despite being one of our better players this season.
