Manchester City winger Riyad Mahrez had three luxury watches worth more than £300,000 ($370,000) stolen when thieves raided his penthouse apartment, according to British media reports.
More than £50,000 in cash along with Cartier bracelets and rare football shirts worth up to £150,000 were also taken from the Algeria international.
The watches were reported to be a £230,000 Richard Mille timepiece, a £40,000 Rolex Daytona and a £35,000 Rolex Day Date.
Mahrez, 29, was said to not have been at home when the offenders used a key fob to access his apartment and three others in the Manchester city centre block on 24 April.
The Sun quoted a letter sent to residents which read: "Four apartments were accessed without authority using a fob which had general access throughout the building. The fob in question is now in our possession, has been fully deactivated and cannot be used again."
