Last summer, when it looked inevitable that Suarez would leave for Real, I suggested that we could do an exchange with Di Maria + cash (obviously I'm happy we kept Suarez in the end, if that's not clear to someone) Anyway, Di Maria is having a great season. He is kind of like Raheem, everybody thought he was just a winger, but now a manager is reaping the rewards of playing him through the middle.
The only downside with him is he usually runs out of gas in the 2nd half. But when he is "on" he is completely unplayable.
