He said:"Arsenal might look in January and think, 'You know what, we're third in the league, we're second in the league, we've got a really good chance this season of finishing in the top four.' And they will have to go out and get one. Their fans were very upset when the window closed and they didn't get one."Thomas Partey is always going to be injured. He's very injury prone. [Granit] Xhaka's been outstanding, [Albert Sambi] Lokonga is still up and coming but they need one more."He continued:"It was strange that they didn't fill that position. Especially when they know Thomas Partey is not going to play a lot of games this season because he's always injured. They need to definitely get one in during the January window."Earlier this summer, the north London outfit were in pursuit of Leicester City's Youri Tielemans and Aston Villa's Douglas Luiz.
