Mourinho warned United could face a "difficult" season if the club failed to sign new players, but he is insisting he will be content to work with the players in his squad in comments that may not reveal his true feelings after a disappointing few weeks of transfer business.
Brought in from from Ukraine to bolster United's midfield ranks, Brazil global Fred is the marquee signing in what has been a frustrating transfer window for Jose Mourinho.
The German worldwide, however, rejected a move to the club, citing doubts on United's inability to win the UEFA Champions League as reasons.
Leicester also spent heavily on seven new players with a £104.3m outlay, topped by Championship prospect James Maddison (£24m) but also secured the services of former West Brom captain Jonny Evans for just £3.5m.
Little more than four months after Manchester City won the 2017-2018 Premier League title, the league returns in full this weekend with 10 matches spread out from Friday afternoon until Sunday, with the piece de resistance taking place Sunday morning, when the reigning champions visit Arsenal.
Having been a player at Liverpool, I certainly know that the club and its supporters demand success.
When all hope to land Boateng and Maguire was dashed, Manchester United turned their focus to highly experienced Atletico Madrid and Uruguay defender Godin.
In terms of the overall net spend, Newcastle made the most with the accounts boosted by £21m from overall transfer activity, while Watford (+£16m) were the only other club to record positive figures.
His style of play does not sit well with the United faithful. Left-back Diego Rico will challenge for a spot in the starting eleven and will surely be a boost for the team.
This leaves another of my old teams, Spurs.
Both have bolstered their squads, and should expect to again in January, but whatever the next 38 games bring, you can bet the fans cannot wait for kick-off.
However, out of those three Wolves look the best equipped to stay the distance.
Tottenham, who have achieved three consecutive top-three finishes under their highly regarded manager Mauricio Pochettino, are still paying for a lavish state-of-the-art new stadium estimated at over £800m and it would appear the mounting cost prevented the club splashing the cash on new players at the same time.
