Willian
The £32 million Brazillian, who was signed from under the nose of Tottenham Hotspurs, has made an instant impact at Stamford Bridge. His Premier League debut was delayed due to his lack of match fitness but when he eventually did make his debut, he set the stage on fire.
A stunning goal in his first Premier League game against Norwich, followed by a tireless 90 minutes against Cardiff has made Willian the one to keep an eye out for.
The Brazillian has blistering pace and can beat his opponents almost at will. He also possesses tremendous ball control which is necessary if one wishes to succeed in the top flight of England.
Add to that his set piece taking prowess and you have one handy, quick and skilled attacker at your peril. The fact that he has not been over-exposed, if exposed at all, to the Premier League gives Chelsea an edge as City will not know what to expect from the Brazilian.
