Manchester City are on course to secure a huge cash windfall as they begin talks to extend their valuable sponsorship deal with Etihad Airways.

The Mirror reports that the aviation firm's deal with the current Premier League champions could be worth an additional £320m, which would help the club slot more comfortably into Uefa's Financial Fair Play regulations.

City are currently three years into their current 10 year deal with Etihad, worth a reported £400m, but the two parties are looking to extend their association by adding another five years to that deal, with an extra £50m a season.

Etihad is already the shirt sponsor for Manchester City and it also owns naming rights to their stadium and the clubs new training complex.

However, the billionaire club are looking for more funds for its new training base at the Etihad Campus, which it will move into at the end of the month.

Manchester City have had branding plans for the new campus approved by the local council, with three additional investors set to be named shortly who will each pay in the region of £25m.
