The trio of Premier League clubs are believed to be very keen on signing young Paris Saint-Germain midfielder Adrien Rabiot.
Despite not being overly well-known the 19-year-old Frenchman is regarded as one of the brightest prospects in Europe and has consequently attracted the interest of the Premier League's elite.
Rabiot is not a product of the PSG academy, though, as he instead came through the ranks of Ligue 2 side US Créteil, and actually spent a few months with Manchester City in 2008 before signing with the Ligue 1 champions in 2010.
With only one-year remaining on his contract at the Parc des Princes, PSG could be forced to sell the highly-rated teenager this summer unless he agrees to extend his contract with Laurent Blanc's side.
The Surrey Mirror are claiming that Jose Mourinho is a big fan of Rabiot and wants him to at Stamford Bridge, but Manuel Pellegrini's City could potentially ignite a bidding war for the player as they're also keen on him returning to the Etihad.
Rabiot would be a much cheaper alternative to Juventus midfielder Paul Pogba who both clubs have reportedly been interested in. Pogba denied speculation that he could leave the Bianconeri earlier in the week.
Arsenal were also credited with an interest earlier in the year, and with Arsene Wenger's knack for turning young French players into stars, a move to the Emirates could be an attractive proposition for the France under-21 international.
Rabiot featured 27 times for Les Rouge-et-Bleu last season and scored three goals in the process.
He's understood to want assurances over where his place in the side lies, as he could be behind PSG team-mates Yohan Cabaye, Blaise Matuidi, Marco Verratti and Thiago Motta in the pecking order next season.
