Chelsea boss Jose Mourinho has already done a lot of business in this summer transfer window by signing a number of star players – Cesc Fabregas from Barcelona, Diego Costa from Atletico Madrid and the Croatian teenage Mario Pasalic from Hajduk Split.

These new signings will help the Blues to win the Premier League title this season, and it is expected that the Portuguese manager is keen to snap up some of the best players to Stamford Bridge ahead of next season as he looks to bolster the quality of youngsters entering the first-team squad, but which player that deserves to be in the Blues this season.

Chelsea midfield department has already been strengthened before the start of the new season, but if they are looking for an another midfield then they should sign Paris Saint-Germain ace Adrien Rabiot, who has 12-months left on his current contract, scoring 3 goals in 27 appearances for the Ligue 1 champions in all competition last season.

The 19-year-old Frenchman could play a crucial role in establishing a much needed balance between Chelsea’s existing department. He would be an ideal addition to the Blues’ squad.
