Mount's transition to United has not been without challenges, with injuries limiting his Premier League appearances to just nine so far. However, his recent performance, including opening his goal-scoring account in a draw against Brentford, demonstrates his potential to make a significant impact for the Red Devils.
"I am sure he will contribute and he will become a big player for Man United," Ten Hag said.
"I was so happy for him. But so sorry for him also that it wasn't the winner. He deserved that moment of glory, maybe it was such a small moment but, for a player who came in and suffered so many injuries and worked so hard all the time, and had so many setbacks, it was so frustrating. And then you think you've scored a winner so we were disappointed when we conceded that goal that makes it 1-1. It makes a totally different mood, as you can imagine."
