He's the club record signing, he's the second highest paid player on the squad, and over the course of 3 seasons he's had 5 managers. Those 5 managers have all had the same issues with him, so it's not the personality or style of play of any one manager. He rarely cracks the starting XI, and he makes few appearances in matches. How many appearances has he made since Conte has taken over? I can't see Conte including him in his plans.
I understand where the supporters are coming from, especially on a day like today. Inferior competition and he couldn't make a positive impact. He looked slow and lazy and turned the ball over. I think Conte has made his mind up about him. Hitchins and Paratici were both sitting behind Conte on the bench today. I think there's a lot going on behind the scenes now that the transfer period is active. Wouldn't be surprised if Ndomeble was a part of any player movement, along with Doherty, Dele, and others.
