Chelsea manager Mauricio Pochettino was pleased for his young squad to get to a semi-final.
The Blues, who have summer signing Christopher Nkunku back from injury, beat Newcastle United on penalties in the Carabao Cup in midweek.
The quarter-final win was nail biting, but Pochettino believes that such wins can help the team gel together.
He stated post-game: We are talking about players that are young, players that arrive and suffer an injury, disturb. Now they meet the team, then they meet the competition.
They need time to start to perform to get the best form. That is sometimes, everyone can judge, yes, you're going to play but the most important is in which form?
Because the expectation is to see the best Nkunku, the problem is we need time for him to perform in the way we expect. One thing is to be available, another is performing to the way we expect.
Too much pressure on him, day by day we are pushing him to arrive as soon as possible to his best to try to help the team in the way we expect."
