The 18-year-old midfielder has been one of the stars of the Ligue 1 season so far, and the Blues are desperate to bring him to Stamford Bridge.

Arsenal, Tottenham and Liverpool have all had representatives at the Par Des Princess watching in the last few weeks, but Jose Mourinho is determined not to miss out on the player.

It’s thought that Chelsea are in the process of putting together a bid – that would be worth £10million up front.

It would be sweetened by Mourinho allowing Rabiot to remain with the French club until the summer, while they would also get a further £5million in bonus payments if he develops as expected.
