The Red Devils boss has found himself under increasing pressure at Old Trafford this season after Manchester United lost two of their opening four Premier League games.
Manchester United slumped to back to back defeats by Tottenham Hotspur and Brighton and Hove Albion before they returned to winning ways last time out with a 2-0 victory at Burnley.
Mourinho has struggled to get the best form out of the likes of midfielder Paul Pogba and some of Manchester United’s other stars in recent months.
And former Chelsea FC midfielder Makelele, who played under Mourinho at Stamford Bridge, believes that the Portuguese coach is once again struggling to adapt to a fresh generation of players.
Makelele is quoted as saying by Metro: “I learned a lot with Jose.
“But at Chelsea he had players like me, John Terry, Frank Lampard. Now it is different. This generation is not the same.
“It has made him tired. He has gone through generation after generation after generation of players.
“Each one is different and maybe he misses the earlier generation. But he still works hard.”
Manchester United will look to make it two wins in a row in the Premier League this weekend when they take on Watford away from home.
The Red Devils are aiming to be one of the main contenders for the Premier League title this season after they finished second and without a trophy last term under Mourinho.
They haven’t won the Premier League title since their final triumph under Sir Alex Ferguson back in 2013.
