Not a problem. Luiz sweeps his penalty into the bottom corner as Gunn dives incorrectly to his right.
Chelsea 1-0 Norwich
Caballero goes to his right at full stretch and palms away the spot-kick. Advantage Chelsea.
Nélson Oliveira now for Norwich...
Chelsea 1-0 Norwich
Willian goes down the middle as Gunn dives early to his left.
It sounds like this penalty shoot out is going old school, so alternate kicks and not ABBA.
Willian is stepping up to take the first spot kick.

Alvaro Morata's is a dive, it's a dive there isn't enough contact there to send him to ground.
Chelsea 1-1 Norwich
Antonio Conte is fuming with the officials.
You get the feeling we are going to hear a lot about the decisions made in this game afterwards.

After a slow start to the game, it didn't half liven up! Absolutely crazy second half and extra time!

Will: Great game for a non-Chelsea fan!

SAVE!
Willy Caballero holds onto Timm Klose's header.
What a game!
Chelsea 1-1 Norwich
Now Norwich have a free kick just outside the Chelsea area.
They couldn't, could they...?
Chelsea 1-1 Norwich
Late change for Norwich as Marco Stiepermann comes on. A penalty specialist? Or a bit of height for the final minute or two.
Stiepermann replaces Todd Cantwell.

It's another incident that I've seen given in the past - but for me Alvaro Morata goes down very easily there. It's a tough one though, because there is contact, so he's within his rights to go down. I don't envy the referee.

It was a dive. He's booked Morata after he went down far too easily. A really poor dive, he went past Zimmerman. We talk about VAR but we have to cut out diving.
That was a good decision, well done Graham Scott
Chelsea 1-1 Norwich
Now Alvaro Morata is sent off!
What drama!
Morata was booked first for being deemed to have dived before getting a quick second yellow for protesting the decision.
Alvaro Morata goes down inside the penalty area under a challenge... penalty? The referee blows his whistle but again favours Norwich!

That is a poor tackle from Pedro.
When you get booked for diving in the second half you are putting yourself under pressure.
