Manchester United midfielder Mason Mount had to be substituted off inside the opening 15 minutes of Sunday's derby clash with Manchester City.
Mount's time at United has been plagued by injury issues but he had been training and playing well recently and was therefore selected to start at the Etihad Stadium ahead of Marcus Rashford and Alejandro Garnacho.
Reacting to Mount's latest setback, former United captain Gary Neville described the situation as 'demoralising'.
Neville also suggested that Mount would be feeling like he was 'letting everyone down'.
