Ruben Amorim took charge of his first Manchester derby this weekend as his Manchester United side came face-to-face with a struggling Manchester City side, and delivered a shock 2-1 win.
While Manchester United's two late winners rocked both the Etihad and a Manchester City side who looked destined for a 1-0 win, there were few highlights in an opening hour of football that largely failed to provoke any reaction from either side.
Even with Josko Vardiol's opening goal there were few memorable moments in Sunday's opening half, however, tensions did boil over just minutes before the break when a Kyle Walker trip left Ramus Hojlund on the ground - delivering the only resemblance of life either side showed during the arduous opening hour of football.
Hojlund who was least pleased with Walker's attempt to stop him from competing for a long kick out wasted no time making his feelings known, racing over to the Manchester City defender and squaring up to him head-to-head.
Despite the minimal contact from a furious Hojlund, Kyle Walker hit the ground and began rolling around like a sack of potatoes, further infuriating both sets of players who got involved in some half-hearted pushing and shoving.

Roy Keane slams Kyle Walker's first-half fall
Unsurprisingly Roy Keane had little issue with the handbags between the two sets of players but was infuriated by the antics of Walker, with Keane slamming both his fall and his character in a scathing rant.
The Corkonian was on Sky Sports Super Sunday alongside former Manchester City star Micah Richards when he was asked about the incident that saw both Hojlund and Walker yellow-carded, and he didn't mince his words responding.
How can Walker go down like that? He must embarrassed to go down like that, an experienced player.
This ain't contact, look at this, I don't know the guy, but I'm embarrassed for him. It's embarrassing.
While in and of itself Keane's analysis of Walker was scathing, his reaction to Micah Richard's insistence Walker was 'better than that' seemed even more damning, with Keane left questioning the defender's character.
Richards: He's better than that.
Keane: Is he, I'm not so sure.
Richards: He is better than that.
Keane: I'm not so sure.
It was a scathing assessment from Keane, who was visibly annoyed by the Englishman's fall before halftime.
Ultimately it was Hojlund who would have the last laugh as Ruben Amorim opened his Manchester Derby account with an 88th-minute penalty from Bruno Fernandes, followed by a shock 90th minute goal from Amad Diallo that secured the most surprising of results for Manchester United.
The antics of Kyle Walker will only dampen the mood of a Manchester City side who have now just one win in their last five performances and our fifth in the Premier League, a point behind Forrest and nine behind leaders Liverpool.
