The Red Devils defender is facing an uncertain future at the 20-time English champions under Jose Mourinho following a string of poor performances.
Mourinho hasn’t been afraid to criticise Shaw in the British media to heap further pressure on the 22-year-old full-back despite his recent comeback from a broken leg.
The 22-year-old defender has only made 62 appearances in the past three and a half seasons at Manchester United due to injury and form problems.
Shaw has been linked with a potential reunion with Mauricio Pochettino at Tottenham Hotspur after the pair worked together at Southampton.
Mourinho took off the former Saints defender at half-time in Manchester United’s 2-0 win over Brighton and Hove Albion in the FA Cup before criticising the left-back in the media again.
BBC Sport reporter Stone suggested that Shaw and his camp are coming to terms with his bleak future at the 20-time English champions.
“The criticism has obviously gone down badly with Shaw,” Stone told BBC Radio 5 Live. “I’m told he is upset by it.
“The people around Shaw are angry at a player being singled out. A 22-year-old player. He isn’t long back from a broken leg.
“It isn’t the first time Mourinho has had a go at him.
“The realisation is dawning on Shaw and the people around him that his future is best served away from Manchester United.”
Manchester United finished in sixth place in the Premier League table to regress under Mourinho last term.
However, the Red Devils won the Europa League and the League Cup in the 2016-17 season.
