What Jose Mourinho said at half-time to inspire Man Utd's derby comeback

Raiola launched a verbal assault at Guardiola last month to continue their long-running feud

The best goal difference ever recorded at the end of a season in the top flight stands at +71, set by Chelsea in 2009-10 with Guardiola's side now sitting on +66 with six games to play.

It seemingly remains only a matter of time before City, who are still 13 points clear, take the title but the manner of the loss was shattering coming soon after Wednesday's Champions League defeat at Liverpool.

Vincent Kompany opened the scoring with a header which seemed to echo his victor against United back in the third-last game of the 2011/12 season - a goal which set up City's first title of the Premier League era - before Ilkay Gundogan scored a beauty on the swivel with 30 minutes gone.

In his post-match interview, Mourinho stated: "I gave them examples of many matches, teams losing 2-0 can recover".

The improvement has been a slow grind at times but the win at City was like the first green shoots of spring for United.

"We're not as bad as people say we are".

Guardiola added more spice to an already hotly-anticipated clash when he claimed on Friday he had been offered the chance to buy Pogba two months ago by the player's agent Mino Raiola.

Mkhitaryan played for United, alongside Pogba, until he joined Arsenal in the January transfer window.

"That's what he was brought in to do and today was a big, big turnaround for him". Pep Guardiola's men are still the favourites to be the league champions, and getting that a win with six games to go is just a formality. "At half-time I said I wanted my defenders to be more confident and need to see more from Jesse Lingard and Alexis Sánchez, but I told my midfield players they didn't need to improve".

United, which didn't manage a shot on target in the first half, netted three times after the break.

His team has also been unfairly held up against Pep Guardiola's City side, a team whose foundations were being laid long before he arrived from Bayern Munich two summers ago.

Ilkay Gündogan then doubled City's lead on 30 minutes when an absolutely lovely turn in the box. The home fans were in dreamland and City should have extended their lead before half-time but Raheem Sterling failed to hit the target with two guilt-edged chances.

Of course, Pep Guardiola's pre-game comments had added a whole lot of spice to an already tempestuous affair and United's record-signing, came out like a Formula One vehicle out of the blocks to single-handledly level the tie.

The first of City's Premier League titles came in 2012 as City edged out United on the final day of the season when Aguero scored in the 94th minute against Queens Park Rangers.

The talk about Paul Pogba was an unwelcome distraction for Mourinho ahead of the Manchester derby, with his side going into the game looking to cement second place.
