Manchester United made an unsuccessful bid to sign Diego Godin from Atletico Madrid with just hours remaining in the window, while potential moves for Harry Maguire, Toby Alderweireld, Jerome Boateng and Yerry Mina failed to materialise.
Mourinho struggled to hide his frustration with the club’s lack of transfer activity when speaking at a pre-match press conference on Thursday, but the Portuguese insist his squad is united ahead of the new season.
Asked if he had the tools to compete without new signings, Mourinho said: “I have my players, I like my players, I like to work with my players.
“One lie repeated 1,000 times is still a lie, but the perception of the people is that it’s true but it’s still a lie.
“So, when you repeat 1,000 times that my relationship with my players is not good, it’s a lie that repeated 1,000 times is still a lie.
“But again, the perception of the people that read can be different, but I like my players and my group. I enjoy the last season, the fight to finish where we finished and to manage the best position in five or six years.
“I’m going to enjoy this season. Again, I know the words you want me to say or not to say. It depends on the music, but works for me don’t come easy.
“Let’s play football and by the end of November or December, you don’t need words. You will see which teams are candidates.”
While the domestic transfer window has now closed, the majority of European clubs still have until August 31 to conclude their business.
