He will be assessed in the coming weeks, and will see a specialist for treatment. https://t.co/4nyPL7HgWjPartey's thigh injury is similar to the one he suffered last season against Spurs, which kept him out for a number of weeks. Arteta told the conference:"It is a little bit ambiguous but he has a significant injury. We have to keep assessing him but he’ll be out for some weeks."However, sports injury expert Ben Dinnery, who runs the Premier Injuries website, predicts that Partey could return sooner than people think based on his previous setback. Dinnery told Football Insider:"I understand that it’s around the same area as a previous thigh injury from 2020. He picked that one up in the North London derby and it lasted around that five-week period.""If we’re looking to base it on that in terms of severity, he could return in a similar timeframe. Funnily enough, that would coincide with the North London derby again."He added:"He is meeting with a specialist to help identify whether there is an underlying issue that would explain why this has come up again. He is so important to that Arsenal team. It’s night and day in terms of points per game when he is and isn’t in the team."Connor Humm@TikiTakaConnorArsenal win percentage 𝐖𝐈𝐓𝐇 Thomas Partey in the PL this season: 65.2% Arsenal win percentage 𝐖𝐈𝐓𝐇𝐎𝐔𝐓 Thomas Partey in the PL this season: 33.3%09:17 AM · Apr 8, 20221699117Arsenal win percentage 𝐖𝐈𝐓𝐇 Thomas Partey in the PL this season: 65.2% Arsenal win percentage 𝐖𝐈𝐓𝐇𝐎𝐔𝐓 Thomas Partey in the PL this season: 33.3% https://t.co/pBEGLxAxIMArsenal desperate for Thomas Partey return ahead of Premier League run-inThomas Partey has been a key member of Mikel Arteta's team this season.
