Exactly. But at least he knows that he isn't technically gifted enough with the ball at his feet and doesn't try something fancy near our goal ala Legrottaglie, which results negatively to the team instead.
His main duty is to protect his goal, and he's pretty damn good at it.
to be honest, i've only seen Di Maria play once this season, the first leg against Liverpool, and i've got to say, he really impressed me, and if they didn't have shitty strikers, he would have ended the night with like 4 assists!
He is the next legendary Italian defender, I expect to see him as their standout player this summer.
