The previous league match saw them batter Queens Park Rangers 4-0 so a convincing performance was needed against the Foxes to prove there was genuine forward motion.
The first half was enjoyable to watch with both teams getting onto the scoresheet. The second half started sluggishly with United in control but seeming to have lost some of their earlier momentum, but a goal from Ander Herrera 12 minutes in put them 3-1 up.
The Red Devils looked like winning comfortably until everything just went wrong for them. In the space of 21 minutes Leicester City were awarded two penalties, Tyler Blackett was sent off and the promoted club had scored a total of four more goals to end a quite thrilling match 5-3 to the home side. While powerful upfront United appear seriously weak at the back and this is now their worst league start ever.
Here are five other things we learnt about United this week.
United are not as big as they once thought
During the summer transfer window United were linked with many players from many clubs, particulary Bayern Munich.
Toni Kroos, Thomas Muller, Arjen Robben and Bastian Schweinsteiger were all possible targets but Bayern manager Pep Guardiola has dismissed claims that any of his squad had any real interest in a move.
Strangely Guardiola insists that had any of his players actually wanted to sign for the 20 times Premier League winners fees would have been an issue as ‘they (United) didn’t have enough money’ despite the English giants going on to spend £150 million this summer alone.
With 31 league goals from 30 appearances last season for current club Real Madrid, Cristiano Ronaldo is a player any team would put on their wishlist.
Ronaldo has previously committed his future to the Spanish giants but every so often there are rumours that the superstar would like a return to his much loved Old Trafford.
Following the losses of Angel Di Maria, Gonzalo Higuain and Mesut Ozil in the last few seasons, word is that Ronaldo has grown weary of his team constantly changing.
United manager Louis van Gaal was recently asked if he was interested in this possible signing to which he noted might be ‘possible’ but also added that Madrid were unlikely to sell him.
Former United vice-captain Patrice Evra has revealed that he was forced to leave Old Trafford due to personal problems.
The 33 year old was at the club for eight years and even signed a one year contract extension back in May though ultimately signed for Italian champions Juventus.
Once considered as one of the league’s best left-backs Evra says he is very happy at his new club and that it was the only team he considered once he had decided to leave United.
Young reveals pigeon prank problems
Just when everyone had begun to remove the image of a bird pooing into the mouth of Ashley Young, the winger has reminded us all by trying to explain the unbelievebly gross incident.
Taking place during the Red Devils opening game defeat to Swansea, Young insists he didn’t notice anything odd saying ‘you would have seen a reaction from me’.
Naturally the 29 year old has had to endure many a joke about the both hilarious and cringe-worthy event from his unsympathetic team-mates who he revealed have resorted to pigeon related dressing room pranks!
Some United supporters may be disappointed that LVG has failed to hit the ground running considering all of his new expensive signings but Bayern Munich’s Arjen Robben has still tipped him to turn things around.
The 30 year old Dutchman has worked under Van Gaal for both club and country winning the Bundesliga and coming third in the 2014 World Cup.
Robben believes the 63 year old can make United play better as a team and as individuals and expects his old boss to lead the club back into the Champions League.
United Supporters. Do you still think LVG is the right man for the job? Do United need to strengthen their defence come January? Let us know what you think below or tweet us @LaFootyettes.
