The midfielder has missed the previous month after suffering a thigh injury, although the Gunners say the summer signing from Atletico Madrid is back with the first-team squad and will be ready to return to action very shortly.
Arsenal confirmed on Thursday that Partey is back in training but that he will be assessed regularly in the build-up to the FA Cup clash, in which the north Londoners will begin their defence of the FA Cup having beaten Chelsea in the final last season.
They face Newcastle at Emirates Stadium on Saturday evening, with Mikel Arteta’s men having finally found some form following a terrible start to the Premier League season.
Arsenal have won their last three games and will get another big boost should £45 million ($60m) summer signing Partey be available for action.
Arteta has been eagerly anticipating Partey’s return, saying earlier this month that having the Ghana international back will be like having a whole new signing at Emirates Stadium.
He said of Partey: “We are in January and I think he’s played two and a half games. That’s all and he was our main signing.
“We’ve been missing him. He brings something different to the team, he’s a player with an enormous talent, but as well someone that can transform the team the way we want.
“It’s great if we can have him, keep him healthy and I think he will contribute in a really positive way.”
Partey has made six appearances for Arsenal in the first part of the 2020-21 season, five of them in the Premier League.
