Mourinho humiliated the defender over the weekend as he substituted Shaw at half-time against Brighton before publicly hitting out at the left-back after the 2-0 win.
The United boss suggested Shaw was defensively inept and Mourinho is now being accused by some of his players of bullying the young Englishman.
The Telegraph claim the board are concerned Mourinho’s public outbursts against Shaw will cause his transfer value to plummet.
Mourinho raged with Shaw during the first half of the FA Cup quarter-final against Brighton as he shouted instructions, and it is not the first time the United boss has hit out at the full-back.
Shaw has been on the receiving end of several scathing public attacks from Mourinho and the outbursts have not gone unnoticed by United players.
Some senior figures in the dressing have become so concerned with Mourinho’s treatment of Shaw, they are considering confronting their manager about the issue.
Mourinho’s staff are also thought to share some of the players’ concerns. Meanwhile, Shaw’s contract is set to expire in the summer and he is privately angry with the criticism from Mourinho.
Shaw is thought to be considering whether his future lies away from United and Mourinho, but he does have the backing of much of the figures inside the club.
What Mourinho said after the match…
‘It was a decision was one player for another player in the same position. I wanted to defend better, I want my defensive line to be more solid in relation to a few, not many.
‘But a few offensive movements they made from the sides and I want more personality in the team because many many times I felt that Matic was an island of personality of desire and control surrounded by not water but lack of personality, lack of class and lack of desire.
‘It was my decision. My reason is that we work on the pitch on certain kinds of movement, with the two full-backs being aggressive to make space for Matic and McTominay. I couldn’t change them both, I decided Luke because Antonio was at least capable defensively.’
Mourinho has questioned Shaw’s commitment to his career, as well as his fitness levels in the past, but did say in February that he would be receive a contract extension.
But, the 22-year-old’s relationship with Mourinho seems to have gone off a cliff since then and there is now seems no guarantee Shaw will be handed a new deal.
Shaw has played 19 this season, only six of his 16 Premier League appearances have been starts.
