Helsea suffered a third successive FA Cup defeat as Liverpool emerged victorious after a dramatic penalty.
Cesar Azpilicueta and Mason Mount missed the shootout after Marcos Alonso and Christian Pulisic got close in normal times.
James Robson was at Wembley to rate Chelsea players.
Edouard Mendy 7
Crucial save to deny Diaz early on. Relied on its woodwork to save it on other occasions – but its handling was superb.
Trevoh Chalobah 7
I really had a hard time keeping up with Diaz. Cleared the line when the Colombian entered early. Grown up in the game impressively.
Thiago Silva 8
Absolute class. As Chelsea looked in danger of being overwhelmed, he kept a cool head with calm use of the ball and clever positioning. How he followed Diaz in a 90and-minute break, only he knows.
Antonio Rudiger 7
Did well to keep Jota silent on his side – but often stretched as Liverpool poured numbers forward.
Reece James 8
I spent a lot of the first half trying to help Chalobah. After the break he pushed much higher up the pitch and that forced Liverpool to retreat. A good defense as the game progresses.
Mato Kovacic 7
Such a player with a big game mentality and it was needed, especially in the first half when Liverpool were on top. Showed the ball consistently and won possession at key moments. Remarkable, he lasted over an hour with an ankle injury.
Played a huge role in the fight against Chelsea in the game. His calm head was crucial in keeping his teammates focused in the eye of the storm.
Marcos Alonso 8
He could have had a hat-trick. Really troubled Liverpool by playing so high. Forced a stop, hit the bar and put another chance right wide.
mason mount 7
I came back to cover James and Chalobah after Liverpool’s meteoric start. Will have required enormous amounts of energy as he also advanced in search of opportunities.
Christian Pulisic 7
Enjoyed playing in a double 10 behind Lukaku and found so many spaces to hurt Liverpool. Should have scored at least one of the two chances that came his way in the box.
Romelu Lukaku 6
His best job was dabbing at the other Chelsea forwards, but he didn’t pose enough of a goal threat.
N’Golo Kante (Kovacić, 66) 7
A significant injection of energy when he took office. Came into extra time to win the ball and disrupt Liverpool’s flow.
hakim ziyech (Lukaku, 85) 5
It looked like a smart change, who could use his pace to run on Liverpool’s tired legs. Didn’t pose enough of a threat to worry them.
Cesar Azpilicueta (Chalobah, 106) 5
Came to play in his 13and grand finale for Chelsea.
Ruben Loftus-Cheek (Pulisic, 106)
Has to be one of the weirdest FA Cup cameos of all time. Came on as a centre-forward. Hooked after 14 minutes.
Ross Barkley (Loftus-Cheek, 119)
submarines: Kepa, Werner, Saul, Sarr
