United were held to a one-all draw at Old Trafford by newly promoted side Wolves on Saturday.
Mourinho’s side struggled to stamp a solid win after their impressive show-off against Young Boys in the Champions League last week.
Former boss Sir Alex Ferguson was welcomed back to Old Trafford since undergoing a brain surgery in May. However, his return could not drive the Red Devils to a win.
Manager Mourinho expressed deep disappointment after their loss, saying, “I am more disappointed today than against Tottenham.”
Striker Alexis Sanchez failed to rise to from the dust after enduring a frustrating last season.
The 29-year-old has been backed by Mourinho since the media slammed the Chilean with criticisms for failing to gel in at Old Trafford.
Obviously very disappointed and unhappy with his frontman, Mourinho criticised his lack of enthusiasm, and would not spare the rest of his attackers.
He added: “I was expecting more from my attacking players.
“There was not enough creativity, movement or dynamism.”
Sanchez tops the list as United’s highest paid player, but so far he hasn’t shown much of his worth on the field.
It was clear is staggering form had drained Mourinho of the little patient he had for the former Arsenal star when he subbed him after the hour mark, with Anthony Martial, hoping to change the dour flow of the game.
But the change did little to fix the problem and United will count themselves lucky not to have lost to Wolves who spurned some chances.
Sanchez has managed just three goals and six assists in 2 appearances since joining earlier this year, which is very poor.
