I didn't actually say that is why Willian was signed but Mata is average out wide. When I look at the Chelsea team I want to see skill, pace and power on the flanks with the genius of Mata in the middle. Then I feel we are capable of beating the likes of Madrid, Barca, Byern ect. Starting with Mata lw, rw against a side like City or Byern you know that flank is pretty much of no use to us throught out the game in terms of attacking directly. In Matas first season we saw that a lot.
