Arsenal midfielder Thomas Partey is expected to be out for three rounds due to injury, according to the club's medical staff. The Ghanaian midfielder has been ruled out of Arsenal's Premier League match against Burnley on Saturday and the FA Cup third-round tie against Nottingham Forest next week.

Partey suffered an ankle injury during Arsenal's win over Manchester City last weekend and was unable to continue in the game. The 26-year-old has been a key player for Arsenal this season, playing in all but one of their Premier League matches so far this year.

The news comes as a blow for Arsenal, who have struggled defensively this season. Partey's absence will be particularly difficult as he provides cover at midfield, with Gabriel Martinelli also struggling with injuries.

It remains to be seen how long Partey will be out for, but it is likely that he will be unavailable for the remainder of the current Premier League campaign, including any potential play-offs or Champions League action.

Despite his injury, Arsenal manager Mikel Arteta will likely look to other players to fill the void left by Partey's absence. He may turn to Aaron Ramsey or Granit Xhaka in midfield, depending on the formation and tactics he chooses.

Overall, it is a setback for Arsenal, but they will hope that they can find a way through without Partey for the rest of the season.
