"The only thing I have to do is work every day like I always do, the only demand on me is the one I put on myself", Mourinho said.
Mourinho has added Victor Lindelof, Romelu Lukaku and Nemanja Matic to his ranks and the former Chelsea, Inter and Real Madrid boss reported a happy camp at Old Trafford in his programme notes. We take a look at the match preview for the clash which kicks off on Sunday, 13th August, 2017 at 16:00 BST.
At the other end of the field, Mourinho is set to reinstate Phil Jones and Eric Bailly as his centre-backs against West Ham.
United were reliant on Swedish striker Zlatan Ibrahimovic, who scored 17 league goals - and 28 all told - before a cruciate knee ligament cut short his season in April. Below is the full squad expected to participate in the season opener.
Should the Red Devils continue their pre-season form and should key players perform, there's no reason why a title challenge can't be achieved.
The Belgian has wasted no time showing the watching world why United splashed out £75m on him over the summer, complimenting three goals in pre-season with a 62nd minute strike against Real Madrid.
Slaven Bilic's men recorded a goalless draw with Sturm Grad before losing to Fulham.
"This season, when I got the call that Matic wants to play for me and for Manchester United, and he can make it happen, I thought he's the flawless player for me".
United are unbeaten in three matches against the Olympic Stadium outfit, winning two and drawing one.
However, United will be up against a West Ham side who've also spent well this summer as they've snapped-up Joe Hart, Pablo Zabaleta, Marko Arnautovic and former United striker Javier Hernandez so I'm expecting a tough game.
Romelu Lukaku will face his favourite opponents.
The 24-year old has had a prolific individual campaign for Everton and anything less than 25 goals for United in his first season with the club under a manager he knows well enough and with better service around him, should be considered failure.
