After Liverpool manager Juergen Klopp criticised United's tactics and said their opening goal should have been ruled out for a foul, he received a response not only from his United counterpart Ole Gunnar Solskjaer but also Jose Mourinho, who was in charge of the club until he was sacked in December a year ago.
This was supposed to be the day when Solskjaer's bubble was well and truly punctured, the day his faith looked horribly misguided.
Manchester United manager Ole Gunnar Solskjaer disagreed with Klopp's assessment of the Origi incident and praised the referee for letting the game flow. A 0-0 or 1-1 draw will see us win, as will a 1-0 or 2-0 victory for the home side.
Manchester United were leading at the end of the first half, courtesy a 36th-minute goal from Marcus Rashford.
Solskjaer couldn't resist as he made a sly reference to that when he was asked about Rashford's goal after the match on Sunday.
During Sky Sports' coverage of Sunday's 1-1 draw against Liverpool, former United skipper Keane claimed they should move for Tottenham star Kane - a suggestion put to the Norwegian ahead of the match against Partizan. While the Italian defender considers that it will take time for the team to bounce back, he believes Allegri will succeed.
Indeed United could have doubled their advantage when Rashford and Fred fired shots just wide of Alisson s goal on the counter-attack.
But despite his team now sitting 14th in the Premier League, seven points adrift of the top four, Solskjaer said it is too early to suggest that United can only make the Champions League by winning the Europa League. "I feel, if we improve as a team, I'll be a success too". "Just go and get him".
Solskjaer (Pictured) is a man under pressure as United are only two points off the relegation zone.
Three of those have come in United's meetings with "big six" rivals - two against Chelsea on opening weekend and then his effort against Liverpool, either side of a blank in the stalemate with Arsenal.
They travel to Serbia on Thursday, October 24 where they face Partizan in a Europa League clash.
However, the Man Utd fans were not impressed by the performance and questioned Ole Gunnar Solskjaer's tactics.
For United, though, the result offers something small to build on.
