City won the title with a record-breaking 100-point haul last season and although Liverpool have been tipped to challenge this term, Reds boss Jurgen Klopp says his team are "Rocky Balboa"-type underdogs".
Those issues have provided an unwelcome backdrop to a hard pre-season, United's makeshift side having suffered defeats to Liverpool and Bayern Munich.
"I'm not confident, I'm not confident and the market closes today, so is time at least for me to stop thinking about the market because the market will be closed", Mourinho said.
The Red Devils coach has cut a sullen figure throughout pre-season with the former Chelsea boss unable to hide his dissatisfaction with Brazil global midfielder Fred being his sides only high profile signing.
USA Basketball, NBA 'blindsided' by new NCAA agent rule
Say Maryland's Kevin Huerter, for example, didn't get drafted in the first two rounds - he'd be able to play for the Terps again. The latter would become effective if the NBA and its players' association allow high school students to enter the draft.

"We made a decision to spend, because we should spend, because we had seven, eight players more than 31-years-old".
"Another point, we don't have more money to spend - that is the truth".
As the season progresses the significance of each game will become more important, but other factors such as styles, potential individual battles and entertainment value will be considered. Mourinho is under no obligation to curry favour with anyone, but his preseason messages to Anthony Martial, Antonio Valencia, Paul Pogba, the club's young players and the central defenders that he clearly doesn't rate have hardly been motivational.
Kourtney Kardashian Agrees She's The Hottest Sibling: "It's Hard Being The Prettiest"
In a series of posts shared with her 23.4 million followers, Kourtney said: "It's not normal to have to relive this stuff". Meanwhile, she and Kim were involved in their own feuding after Kourtney tweeted, "We all have our own priorities".
