Aubameyang has now detailed what makes Partey so special, and how he is already making a difference.
In a chat with the Arsenal matchday programme, he said: "Thomas has been great since joining the club.
"He has integrated so well in the squad.
"He is kind, calm and smiley. On the pitch, we have seen already seen what he will bring us in matches.
"He is so strong physically but yet so good on the ball as well. We didn't really have a profile like this in our squad before. In terms of ball progression, beating the press, going forward, he will be very important for us.
"My family is from Gabon but I also have some roots in Ghana where Thomas is from so we are family too! It is good for some of our younger players as well to have a player like him, of his calibre at training.
“They will learn a lot from him."
