16 mins A Chelsea cross from their right was over-hit and Levi Colwell gained possession on the opposite flank with his back to goal. Under pressure from Miggy Almiron, he sent the ball towards Moises Caicedo in the centre of the pitch but it passed his outstretched leg and fell into the path of Callum Wilson.

The visiting striker accelerated over the halfway line towards the Matthew Harding stand, intent on trying to barge his way between defensive pair Thiago Silva and Benoit Badiashile en route to goal. 

Tempting Silva into trying to tackle him, a deflection left Wilson one one one with Badiashile, but with his opponent half a stride in front of him. Reaching the edge of the box, the Chelsea player looked favourite to clear his lines, but the ball bobbled up and struck his shin, allowing Wilson to nip in, take a touch and hook it to the goalkeeper's right and into the far side of the goal. 1-0

Half time: Chelsea 0 Newcastle 1

90+2 mins A deep cross was sent over by Malo Gusto from the Chelsea right to nobody in particular, only for Kieran Trippier to misjudge the bounce and head the ball down back towards his own goal - presumably believing that Dubravka would come towards the edg of his six yard box to collect.

Instead though it fell into the path of the onrushing Mykhailo Mudryk, who had the simple task of hoofing it into the net.  1-1

Eddie Howe - managing the Magpies for the 100th time (50 wins, 27 losses, 23 draws) - said:

"It hurts a lot - it’s a very similar game to the Paris end-of-game feeling where the lads had committed so much, given everything and led for so long, defended really well but didn’t get over the line.

"Whenever we concede, we concede collectively, we don’t concede individually. As a team we were excellent, our shape was so good, it was a heroic effort. I can’t praise the players enough.

"We probably weren’t as good technically in the second half and we lost our threat.

"A tough ending to the game. It was a really good away performance until the last moments. I didn't see a goal coming at that stage. 

"It's just one of those things that can happen in a football match. We covered space well, limited them to half-chances. There are a lot of positives to take but we don't feel that right now.

"I don't think it's anything to do with anything catching up with us. We conceded late in a moment where we looked like we'd absorbed most of their threat and defended so well. 

"We have to take ownership of what happened but I couldn't be prouder of the players. (I'm) very disappointed to go out."

On Sven Botman:

"It was the plan for 45 minutes for Sven (Botman), trying to build his load back up rather than pushing him too early. We were pleased with his contribution.

On Anthony Gordon:

"It was a shame to see such an important player for us leave the pitch due to a tackle. I haven't seen it again so don't know if VAR was in action whether it would have been a red card. (I'm) Disappointed for Anthony, who wanted to continue. 

"I thought it was a really poor tackle on him and the type of tackle you don't want to see taking one of our attacking players out of the game, and again he's very sore at the minute.

"I'm going on what other people's opinions are and not mine - I haven't seen it myself but people are telling me that they think it's a red card."

On Emil Krafth:

"Emil (Krafth) was too sore to continue - he's got a nasty gash on his shin which is quite sore at the moment."

On Kieran Trippier:

"I'm sure he doesn't feel fantastic because he prides himself on his technical excellence and the quality of his defensive work. He's been a transformative signing for us and glued the dressing room together. He's been the heartbeat of our performances."

Mauricio Pochettino:

"It was a really good game. We suffered when we conceded, it was our mistake. 

"To concede the way we conceded, when we didn't deserve to, it can affect any team, but we reacted really well, dominated the game against a good team like Newcastle, kept pushing in the second half, made some changes and tried to provide the team some impact.

"The most important (thing) in football is to believe to the end. We kept believing. 

"We know penalties are a lottery, but of course talent and quality (matter). Our objective before the game was to go through and now we're in the semi-final.

"I said to the players to always believe until the end. The goal was possible because we believed. Sometimes in football you need some luck, and it came. Credit to the players because they were fantastic. We are so happy. The fans and the club deserve this sort of feeling. It's a big motivation. We are waiting for the draw tomorrow.

"These types of games and the way we went through are important for the development of the team. It’s the same as games when you don’t play well. Both are really important for this group to evolve and develop.

"When you saw the whole squad, including players who were injured and wanted to share their happiness in the middle of the pitch, it looks like we are a healthy group of players that only need time.

"Our responsibility is to guide them and create a platform for them to really improve. With time we are going to create a very good team that can compete, increase the competition, and be in the place Chelsea should be in."
