The Englishman, who arrived at Old Trafford in 2011, has been used as something of a specialist squad player this season, making 20 appearances in total.
It was rumoured that Young was eyeing move away from Man United over the January transfer period, but Mourinho quickly confirmed that the 31-year-old was indeed going nowhere and very much a part of his plans.
But Young, speaking soon after United’s 2-0 win over Chelsea, expressed doubts about his long-term future.
“I have another year left on my contract and a one-year option after that,” Young told reporters. “So if there is anything there to be discussed, you would have to ask the manager.
“I have always said that I want to play as much as possible. What the future holds I am not too sure.”
The Englishman is not getting any younger at Old Trafford; doubts about what comes next are natural for somebody who will want to make the most of his last few years at the top. But Mourinho has found a superb role for Young this season; a kind of specialist hard-worker, drafted in when players are tired and the game requires some extra legs.
He has done this perfectly this season, manifesting admirable levels of discipline and serve in various roles. How long he can keep such continued reliability up, however, is another question.
