United opened the scoring with a stunner from rocket-man Mason Greenwood - with the goal coming out of virtually nothing. Youri Tielemans equalised after half an hour sending the teams down the tunnel at halftime level.
The Foxes went ahead for the first time in the match with Caglar Soyuncu finding the back of the net from close range. Marcus Rashford equalised a few minutes later to draw level once again. But that wasn't it, 20 seconds later, Jamie Vardy scored to put Leicester 3-2 up. Patson Daka eventually rounded off a perfect day for Brendan Rodgers' men in injury time with a tap in at the back post to score his first Premier League goal.
The Evans effect
It was the first time that Jonny Evans had started in the league since April. He was exceptional, and so was the whole of the backline.
In recent times, with Evans battling a problem with his foot, whoever has been in defence for Leicester has struggled. Evans is there to guide and keep things cool at the back, if Evans plays well, they all do. In strong contrast to when Jannik Vestergaard was operating in the same role, things looked shaky and he panicked when being attacked, leaving the other defenders around him to panic at the same time.
The Northern Ireland international has had fans begging for him to be back in the starting lineup, considering how poor the defence has been so far this season. In the three at the back, with Evans occupying the central role, this allows Soyuncu and Daniel Amartey more freedom to play the ball on either side of him. Evans covers, and sweeps, whilst the other two do more running.
It just looks so much more comfortable at the back, where nothing could have been done about the two very well taken goals from the visitors. Rodgers has been crying out for Evans, and hopefully, he's back now for good.
With Wilfred Ndidi being out with an injury, it was always going to be a big question as to who fills his boots. Rodgers opted for a three in midfield, with two wing-backs pushing higher in transition.
James Maddison returned to the starting lineup after a few games being left out, which was probably what was needed. He played alongside Boubakary Soumare and Youri Tielemans. All three of them were excellent.
Tielemans scored a great goal to equalise in the first half - whether he meant it or not, it was awesome. He controlled the tempo of play in the middle of the park by breaking up play, threading passes, he was everywhere.
Soumare played more as an eight alongside Tielemans, a role he isn't as used to after playing more as a defensive midfielder over in France for Lille.
Much like Tielemans, he was everywhere. His dribbling in and out of trouble, his one-touch passing, his terrific work rate. Soumare proved why so many clubs wanted him in the summer, in arguably his best game in a blue shirt.
Then we have Maddison, who hasn't registered a goal or assist since last season. He stepped up for his side and did what he does best. Flair in attack, making things happen. Winning lots of fouls, and Foxes fans can hope that it's the beginning of his retribution in the East Midlands.
For once, Leicester City actually looked comfortable in all areas of the pitch, without their anchor Ndidi.
Firstly, Iheanacho wonderfully set up the first goal after having chants directed at him by travelling supporters, which really was one way to shut them up.
He did so much more than just get that assist. When he dropped deep, forming the connection with the midfield and attack, it opened up pockets of space for Vardy to cause havoc in. He pressed so well, leading to that Tielemans goal. He caused Harry Maguire trouble all game long.
Also, his recent partner in crime, and the goalscorer of the goal that put Leicester 3-2 up, Vardy strikes again!
Now joint top goalscorer on seven with Mohammed Salah, and now four games in a row with at least one goal, his own record is there to be broken.
The 34-year-old took his goal so so well, which he has done on multiple occasions so far this season. First time, outside of the foot, slice into the top corner, it doesn't get much prettier than that.
Nothing could have rounded the game off better than Daka getting in on the act. He scored in stoppage time from a belting Tielemans delivery, and in the ten minutes he was on - he had three shots on target. It's looking good for the Zambian who looks like a real centre forward. A proper natural finisher.
