#4 Anthony Martial (Manchester United)

It is no secret that Martial is looking for a route out of Old Trafford. His agent has made it clear that he wants to leave Manchester United, after falling down the pecking order at the club, particularly after the signing of Alexis Sanchez.
The Frenchman has started just 36 Premier League matches in his two seasons under Jose Mourinho, and that will have contributed to him missing out on selection for the World Cup with France.
He has predominantly played out on the left for United in his time in England, but he is more than capable of playing down the middle as a striker. He has the pace to run in behind defences and is more than good enough in front of goal to be a 20-goal a season striker.
The one issue for Chelsea is that United may not be inclined to sell to a fellow Premier League club, but they may be more prepared to discuss the deal with Chelsea, given that they allowed Nemanja Matic to move to Old Trafford last summer.
