You spoke well mate, But in as much as we know Thomas Partey is not reliable because of injury,I think the club should still keep him and bring in a new holding midfielder that will play his role,but you know if Partey is fit,there is no midfielder that can play more than him when it comes to that holding position where he plays.
I wish Arteta listens to what people are telling him and keeps Thomas Partey because he is so good that Arsenal find it very difficult to lose a games when he is on the pitch and in the middle of the park,and Declan Rice complements him well when they pay together.
Thomas Partey is actually a fairly complete defensive midfielder when he plays in Arsenal midfield with Declan Rice, but the injuries that often befall thomas Partey have often been a consideration for Arteta to bring in a new defensive midfielder who can act as a tandem for Declan Rice in next seasons, Reportedly, Arteta is still trying to retain thomas Partey and give him a guarantee to be included in Arsenal main line up, but even though Arsenal will also bring in a new defensive midfielder, currently Arsenal has been linked with Onana, Casemiro and also Martin Zubimendi, but so far Arsenal have not been very active in getting one of them of that the three defensive midfielders.
Arteta does plan to keep Thomas Partey for at least one more season, but Arteta also needs to be able to strengthen the depth of their midfield next season, and I personally really see Partey staying at Arsenal because after all he is a good, strong and capable midfielder had many positive effects on every Arsenal game so far.
