Brazil global Fred opened scoring for the Red Devils in the 18th minute of the meeting through a Paul Pogba's assist.
Mourinho did not call out Sanchez's performance directly but did criticise his attacking players.
"A fair result. Wolves, by the way, they faced the game, I think they deserve it". They had [it], we didn't. "I don't want to say our improvement has the name of Chris or Victor; the team is playing better and they are part of the team that plays these matches". "Knowing that when you have the ball you have to produce chances and we did that".
The issue of post-World Cup fatigue has been debated extensively be club managers, with Tottenham striker Harry Kane the most high-profile example of those struggling to replicate their best form. "There was not enough creativity, movement or dynamism", he added. They caused United all sorts of problems.
"[The performance] surprised me".
Brazilian midfielder Fred drove home from the edge of the area after a sublime, one touch, deft short pass from Paul Pogba. They [Wolves] were fresh as they didn't play in midweek.
"It is a situation where the players knew perfectly that they press in midfield", Mourinho said.
"Our performance was not consistent, not creative and not dynamic".
"That's the attitude that I like my teams to have every match, and we didn't have that". They had, we didn't. You have 90 minutes to show a different attitude.
After securing the Championship title last season when earning promotion back to the Premier League, Wolves have continued to impress this campaign, having tasted defeat just once from their six league games so far. This is something you learn when you're a kid in the academy. It is a basic law of football, you have to play at the maximum of your potential.
Mourinho introduced Juan Mata, Anthony Martial and Andreas Pereira from the bench in the final half-an-hour and all looked sharp, but the manager was in no mood to praise them.
Ferguson, who managed United for 27 years before retiring in 2013, was on hand to see Brazilian worldwide Fred score his first goal for the club since signing from Shakhtar Donetsk in the summer.
