Chelsea are reportedly close to agreeing a £25m-a-year shirt sponsorship deal with Turkish Airlines.
The Blues have been sponsored by Samsung since 2005, but the Daily Express claims that Turkish Airlines is willing to offer £7m-per-year more than their current contract with the Korean electronics manufacturer.
If completed, the deal will be the fourth largest shirt sponsorship agreement in Premier League history, with Manchester United's £45m-a-year tie-up with Chevrolet being the most lucrative.
Chelsea boss Jose Mourinho, whose side face Sunderland at the Stadium of Light on Saturday, has also hinted that he could extend his current contract with the Stamford Bridge club.
