Willian
When the Brazil international arrived at Chelsea for big money this summer the more paranoid football fans among you might have suggested that Mourinho had only signed him to stop him going to Spurs .
It was easy to see why at the time, he signed for Chelsea on the 25th of August and did not play in the four games following his arrival and in the next four matches he only started once.
However since the Crystal Palace game in December where Chelsea won 2-1 he has been a regular fixture in the starting eleven and very, very impressive.
In the 11 games including and after that Palace match Willian has a 84% pass completion and has made nearly three key passes per match. He wins 58% of take ons and also 58% of tackles.
