Chelsea progressed to the semi-finals of the FA Cup by beating Manchester United in a fiery clash at Stamford Bridge.
The excellent N’Golo Kante scored the only goal of the game as Antonio Conte’s men remain on course for the double.
The Frenchman, who dominated Paul Pogba throughout, fired home from the edge of the box to beat David De Gea.
Ander Herrera had seen red during the first-half for United, before Jose Mourinho and Antonio Conte clashed.
Here are five things we learned.
1. Kante edges out Pogba
They were the two big midfield buys last summer after a fine Euro 2016 with France.
But it was N’Golo Kante who dominated his countryman at Stamford Bridge.
Kante was destructive in front of the Chelsea back four and even popped up with the winner.
Surely the Footballer of the Year.
2. Herrera red changes the game
It was a big call and it certainly affected this one.
Jose Mourinho had his side set up to defend and when Ander Herrera was dismissed, his plans went out of the window.
It was harsh on the Spaniard but you can see why Michael Oliver dismissed him.
3. No love lost between the bosses
Ahead of the encounter, Antonio Conte spoke of the respect between he and Jose Mourinho.
They clashed earlier in the season and it didn’t take long for history to repeat itself.
The Ander Herrera red card didn’t help matters before a late challenge on Marcos Alonso from Antonio Valencia.
Fourth official Mike Jones had a busy evening as he came between the duo.
Safe to say, they won’t be receiving Christmas cards from one another.
4. De Gea remains the best
The Manchester United stopper is having another fine season.
De Gea was well-beaten by Kante but he made a number of fine saves, none better than the stop to deny Cahill.
He is the best in England…and arguably the world.
You have to think United would be a lot worse off without him.
5. The double is on
Chelsea are romping to the Premier League title and they must now be favourites to add the FA Cup to their trophy cabinet this season.
Despite the slender margin of victory they were rarely troubled by United at the Bridge and take on a Spurs side in the last four at Wembley who look likely to be without talisman Harry Kane.
It could turn out to be an even more incredible first season in English football for Antonio Conte than we thought.
Andy Dunn’s player ratings
Courtois 7 – Largely redundant but made one crucial save from Rashford
Moses 6 – Mourinho tactics negated his impact, pressed back more than usual
Azpilicueta 7 – A very calm contribution but hardly stretched by a one-man attack
Luiz 7 – Another Chelsea defender with a cigar on the go for most of the time
Cahill 6 – Seemed to be targeted by Rashford and exposed occasionally
Alonso 6 – Like his fellow wing-back, found himself pinned at times
Matic 7 – Enjoyed the physcial confrontations and grew into the game
Kante 7 – Not at his most eye-catching but stepped up with the breakthrough
Willian 6 – Put in a serious shift but nothing much came off for him
Hazard 8 – MOTM. Flashes of brilliance and his victimisation ended up changing the game
Costa 6 – Put himself around as usual but not to great effect
Fabregas (for Willian, 81)
Zouma (for Moses, 89)
Batshuayi (for Costa, 90)
De Gea 6 – Two great first half save but wrong-footed for the Kante goal
Jones 7 – It is not always pretty but certainly left his mark on the game
Smalling 6 – Standard stuff, some crucial blocks but some rushes of blood
Rojo 7 – The marshalling figure in a packed United defence. Pretty solid
Darmian 6 – Conceded a welter of free-kicks but never less than tenacious
Valencia 6 – Wary about over-committing and not a major factor
Herrera 4 – Sent off. Two yellows a little harsh but a dismissal that has been coming for a while.
Pogba 6 – Relished the physical battle and made his mark on the contest
Mkhitaryan 6 – Had one decent effort before tactical withdrawal after Herrera red
Young 6 – Mainly restricted to defensive duties which he carried out diligently
Rashford 7 – Often a thankless task but selflessly ran himself into the ground
Fellaini (Mkhitaryan, 37) 6
Lingard (for Young, 81)
