Timothy Fosu-Mensah - a contender to play at centre half, but most probably at right back, considering United's options - has arrived at Premier League newcomers Fulham to agree a season long loan after spending past year on loan at Selhurst Park.
The Citizens are looking to retain their top-flight crown under Pep Guardiola after the Spanish head coach got his hands on his first Premier League trophy last season.
In late July the Portuguese said he was confident of getting at least one more signing through the door, but hopes have faded as Thursday's 5pm deadline edged closer.
United start the Premier League season at home to Leicester City on Friday and Mourinho took the opportunity at his pre-match news conference to take a swipe at what he views as fatalistic commentary on his reign from the media, in contrast with praise awarded to unnamed counterparts who fail to lift major honours.
"My view is that, first of all, it is hard for me to believe we finished second because when I listen, when I read - not much but sometimes I do - you [the media] are capable of making people that finish second look like they were relegated, and people who win nothing, finish below us, you make them look like serial winners". "They trained Monday, Tuesday, Wednesday and today, so you can imagine they are not really fit and ready. I won eight championships and three Premier Leagues but I keep saying and thinking and feeling that second position last season was one of my biggest achievements in the game". They [Manchester City] have been playing some great football.
"Since nine years, every season - except the first when I arrived at Barcelona".
"I know there has been a lot of talk about pre-season in the press but I am sure behind the scenes, Jose has been giving them the right amount of work".
