Tottenham boss Jose Mourinho expects Manchester United to eventually start winning titles again.
Mourinho - now manager of United's Premier League rivals Tottenham - is the last manager to have won a trophy in charge of United, guiding them to the Europa League crown in 2017.
"It is a team that is improving year after year," he told Sky Sports. "The younger players are now older, they have more experience now. The players they have bought are players of quality.
"Many of my players, important players for me in my time at United, they are not any more important.
"They have changed their team. Players that worked with me, some of them are not even now selected or they are on the bench so that is a great evolution in the team.
"They have this ambition and this responsibility of winning titles which they haven't done for quite a long time. The last one was the Europa League so they have this motivation, this potential and they are a very good side."
