The Red Devils signed the England international in a £27m deal from Southampton in the 2014 summer transfer window.
The 22-year-old suffered a horror leg break in a Champions League fixture in 2015 to stunt his progress under Louis van Gaal.
The Dutchman’s successor Jose Mourinho has used the Manchester United full-back sparingly since his appointment almost 24 months ago.
In fact, the Manchester United manager has regularly criticised Shaw for his poor performances and his attitude in training.
Shaw was withdrawn at half-time of Manchester United’s 2-0 win over Brighton in the FA Cup quarter-final at Old Trafford earlier this month.
The Red Devils boss was again critical of Shaw, although some pundits have slammed Mourinho for his treatment of the promising defender.
Former Arsenal striker Wright offered Shaw a simple approach to winning over his manager and salvaging his Red Devils career.
“Shaw needs to be getting to grips with training,” Wright told BBC Radio 5 Live.
“He needs to make questioning his fitness is not an issue. That’s what experienced players will be telling him.
“To keep going and to be ready and available. Don’t give Mourinho any excuse.”
Manchester United finished in sixth place in the Premier League table last season but won the EFL Cup and the Europa League.
The Red Devils will take on Tottenham Hotspur in the FA Cup semi-finals at Wembley for a place in the showpiece in May.
