Pep Guardiola praised 20-year-old goalkeeper Arijanet Muric after holders Manchester City reached the Carabao Cup semi finals.
They beat Leicester 3-1 on penalties after a 1-1 draw at the King Power Stadium on Tuesday.
City remain in the hunt for a quadruple this season as Oleksandr Zinchenko scored the decisive spot kick after Muric saved from James Maddison and Caglar Soyuncu.
Christian Fuchs missed for Leicester and Raheem Sterling was embarrassed after he chipped his spot-kick over, although Gabriel Jesus and Ilkay Gundogan scored for City.
Kevin De Bruyne opened the scoring in the first half only for Marc Albrighton’s 73rd-minute leveller to send it to penalties, for a repeat of last season’s quarter final between the sides.
Guardiola said: “We got to the final last season and won so we played to win the game. It was quite similar to last season. The end was the same and last season Claudio (Bravo) was exceptional and this year it was Arijanet.
“I don’t know how the legs will be sustained for the rest of the season but it’s better to be in the semi final than to be out.
“Aro is so big, his reaction is so quick and he took the right decisions. It’s good experience for him. He is a young guy, he is so shy, it’s a nice moment. He deserve the big applause.”
France World Cup winner Kylian Mbappe celebrates his 20th birthday on December 20.
Here, we look at the key numbers from the Paris St Germain forward’s career so far.
£128m – the reported fee paid by PSG to sign Mbappe from Monaco in 2017 – the second highest in world history behind club-mate Neymar.
2 – Mbappe became only the second teenager to score in a World Cup final as France won this summer’s tournament. His predecessor in the exclusive club is Pele.
4 – his goal tally in the tournament, earning him the Best Young Player award.
2 – Ligue 1 titles, with PSG already well on track for another this season. He had won the league with two different clubs by the age of 19 years and five months.
7 – Mbappe’s shirt number at PSG. He took it over for this season after it was vacated by Lucas Moura’s move to Tottenham, saying he saw the “legendary shirt” as an indicator of his progress and ambition.
12 – goals in 11 Ligue 1 games this season.
4 – goals in PSG’s 5-0 win over Lyon. The goals came in 13 minutes.
18 – Mbappe made his France debut aged 18 years, three months and five days.
Paco Alcacer has become the first player in Bundesliga history to score 10 goals as a substitute in a single season.
The 25-year-old has been in inspiration form for Borussia Dortmund since joining on a season-long loan from Barcelona in August.
The Spaniard is currently the leading goalscorer in the Bundesliga with 12 strikes, made even more impressive by the fact he’s been used off the bench in seven out of his 11 appearances in the league this term.
Alcacer has now scored in his first seven appearances as a substitute, netting 10 times in those seven matches, including a neat finish against Dusseldorf on Tuesday.
10 – @paco93alcacer is the first player in #Bundesliga history to score 10 goals as a substitute in a single season, already surpassing the record after just 16 matchdays (previously held by Nils Petersen and Ioan Ganea, 9). Phenomenon. #F95BVB @BlackYellow pic.twitter.com/VRTmvRXvjh— OptaFranz (@OptaFranz) December 18, 2018
