The pacy Argentine winger completed a 5-2 thrashing of the Champions League last-16 debutants with a delightful lob on Wednesday and he should be firing on all cylinders by the time they meet Bayern Munich in the semi-finals later this month.
Di Maria is still one of the side's highest providers of assists despite having sidelined with a string of niggling muscle injuries since the turn of the year and he has only started 12 league games and three in the Champions League.

"I thought it was the end of the season for me but I am back in time for the most important games."
"The competition in the squad is very good," said Kaka, one of the world's most expensive players who is not guaranteed a place in the starting XI.
"Obviously there are players who are decisive but our strength has been the group."
