Thomas Partey is set to miss key matches for Arsenal after injuring himself during a preseason friendly match against Chelsea.

He was caught by a heavy challenge from Chelsea's Ruben Loftus-Cheek and was forced off five minutes before half-time, with the Gunners going on to lose the game 2-1.

Images of the tackle appear to show the 28-year-old's foot caught beneath the weight of Loftus-Cheek's thigh and his ankle turned in an unnatural position.
His club has revealed that the midfielder will miss at least three weeks of action with his latest injury and is expected to miss Arsenal's remaining preseason game while he will not take any part in their opening game against Brentford.
Arsenal have said of Partey in a fitness update on the club's official website: "Thomas sustained an injury to ligaments in his right ankle during the friendly match against Chelsea last Sunday.

"Thomas continues to be assessed and is expected to be back in training in approximately three weeks.

The Ghanaian midfielder will miss Arsenal's friendly derby date with local rivals Tottenham on Sunday.

They will then be involved in a Premier League curtain-raiser against Brentford next Friday which will come too soon for the former Atletico Madrid player.

A testing start to the season then takes in a home date with Chelsea on August 22 and a trip to Manchester City six days later.

Domestic action then shuts down, giving Partey chance to work on his fitness before the Gunners face Norwich on September 11.
