Young has so far made 29 appearances for the Red Devils this campaign and the ex-Watford and Aston Villa winger has told Sky Sports that his flexibility to play anywhere on the field could be helpful for England in the World Cup in Russian Federation.
If Shaw can not get back to the first team picture by May, it is unclear how he would stay at Old Trafford beyond the summer.
Shaw, who has seven global caps, has not played for England since March 2017.
"I'm doing my best and I'm happy to work with him, I'm happy to be part of his team, this club".
But the 55-year-old looks to have the backing of his players, with Young saying his team-mates know where they stand.
It's not the first time that Shaw's people have briefed the media with a similar line, but with a manager who doesn't rate him and a high-priced replacement likely, Shaw may not have much of a choice.
"As a manager you've got to find a way to get the best out of him and I don't think Mourinho has done that". He has suggested that so called "flair", players will choose to move to other club's when they see the stodgy and lifeless performances United have been putting in as of late.
His last global appearance came in last November's 0-0 draw with Brazil at Wembley, after a four-year absence from the squad.
Neville, who played over 600 games for United and won eight Premier League titles, insists Shaw has the potential to revive his career at the Theatre of Dreams.
He missed out on the 2014 World Cup and is keen to be involved when Southgate announces his team for this summer's tournament in Russian Federation.
"I've got to play well at United to get that recognition, and now I've had that in this call-up, I've got to impress".
Not that we've got anything against lyric sheets being passed around, but it all seems like a lot of effort to go to when the most popular chant at United for the past couple of months only has one word anyway.
