That man is the person who produced arguably the greatest moment of Mata's career. The scorer of the winning goal in the 2010 World Cup final: Andres Iniesta.

There are still questions over his best position at Old Trafford, but the Spaniard has performed admirably on the right flank.
He often cuts inside to take up a more central position but has not been given the opportunity to make role behind the striker his own.
