The Red Devils forward has often threatened to go on a prolific run of form but Martial’s biggest problem has been sustaining his performance level over a number of months in recent seasons.
October was a good month for the France international after Martial got on the score sheet four times in three Premier League games to help Manchester United remain unbeaten.
Martial won a penalty before the 22-year-old got on the score sheet in a 2-1 win over Everton last weekend to earn the plaudits for a man of the match performance.
He continued his prolific run with the equaliser in Manchester United’s 2-1 victory at Bournemouth on Saturday lunchtime to score in his four successive game.
However, the former Lyon attacker was criticised by his manager in the second half of the 2017-18 season, as he started 18 games and made 12 substitute appearances.
His national team manager, Didier Deschamps, opted to leave Martial out of his France squad for the World Cup as les Bleus went on to win the major tournament.
Meanwhile, his compatriot and former AS Monaco team-mate Mbappe won the World Cup less than a year after surpassing Martial as the most expensive teenager in world football.
Mourinho’s critics have been quick to blame the manager’s unwillingness to give young talent a chance to shine as one of the chief reasons for Martial’s decline.
While Collymore believes Mourinho cannot take credit for Martial’s recent upturn in form, the Liverpool FC legend wants to see more from the France talent.
“Martial came to the club and was meant to go on and be like Kylian Mbappe and shape the next generation of forwards,” Collymore told the Daily Mirror.
“He is still miles off that kind of form.
“Luke Shaw was supposed to be England’s left back for ten years and is just getting back into the frame with the national team.
“Congratulations to both of them for keeping their heads down and for their professionalism.”
Martial’s move to Manchester United in the 2015 summer transfer window came as a surprise after the Red Devils spent £36m to recruit the France international from AS Monaco.
The 20-time English champions fended off interest in Martial in the summer to retain their talented number 11.
Even Mourinho’s predecessor Louis van Gaal wasn’t afraid to critique his prolific talent despite Martial scoring 17 times in 52 games in his debut season at Old Trafford.
