#4 Jamie Vardy (Leicester City)
Leicester's main man has been linked with a move to Stamford Bridge consistently ever since he guided the Foxes to their remarkable league triumph in 2016 but the move has never materialized. At 31, though, Vardy doesn't have much time left at the top and to get a big money move so the timing could be good for both parties.
The Englishman is playing some of his best football this season: he has linked superbly with Riyad Mahrez, just as they did together under Claudio Ranieri in 2015/2016.
Vardy's style of play - running in behind defenses using his speed and acceleration to get in on goal - represents a differing option to Morata's aerial strengths if that isn't working out.
Even if he was used solely as a substitute, Vardy's pace and skill coming off the bench would be an amazing weapon to use on tiring opposition defenses. Vardy has all the attributes to be an effective impact player late in a game.
His former Leicester teammate Danny Drinkwater is already at Chelsea and this would enable him to settle into his new surroundings and would benefit the club on the pitch too, as the duo enjoyed a great partnership at the King Power Stadium.
