LEICESTER -- Pep Guardiola dismissed suggestions that Manchester City could win four trophies this season as unrealistic after his side reached the semifinals of the Carabao Cup.
City needed a penalty shootout -- for the second round running -- to get past Leicester City and reached the last four after the game finished 1-1.
His side are 11 points clear at the top of the Premier League and have a favourable draw against Swiss side Basel in the Champions League round of 16, but Guardiola ruled out winning all three competitions along with the FA Cup.
"That is not gong to happen," Guardiola told a news conference. "Of course not, that is unreal -- what we are living is unreal. That is not going to happen.
"The situation of winning 16 games in a row, qualifying for the Champions League two games before the group stage has finished and now playing here with a lot of young players -- that is not normal in football.
"You drop points and lose competitions but of course it helps us a lot to keep the record going but I'm not thinking about how many titles."
Guardiola played a youthful side with academy products Phil Foden, Tosin Adrabioyo and Brahim Diaz starting, while fellow City graduates Lukas Nmecha and Tom Dele-Bashiru making their first-team debuts as substitutes.
But it was Claudio Bravo, who was the hero again. The Chilean saved three penalties in the previous round against Wolverhampton Wanderers and saved again from Riyad Mahrez after Jamie Vardy had missed the previous spot kick.
Guardiola celebrated with the supporters after the victory and has urged his team to enjoy the moment in the locker room.
"I am so happy. We want to go through but you can't play four competitions with the same players -- it's impossible," he added.
"The young players made a step forward and I think it's a good sign for the club, for the academy, for everybody, that's why I'm so happy. I said in the locker room: 'celebrate again.'
"And the penalties again, Claudio helped us to reach the semifinal. In the big teams you have to handle the bad moments."
City look unstoppable in the league, but Bernardo Silva -- who scored the opener on the night -- joined his coach in taking nothing for granted.
"It's been a great first half of the season and I hope we can keep doing our job, keep winning games because this team deserves to keep winning because of the way we play and the spirit,'' he told Sky Sports Football.
"We will keep working hard to keep giving our fans victories and at the end of the season we will try and celebrate something.''
City would have won the tie in normal time had it not been for a controversial penalty when Demarai Gray went down under a challenge from Kyle Walker.
Foxes boss Claude Puel, who was already without Wilfred Ndidi, who was banned for diving, insisted it was a penalty and claimed they should have a second for a challenge on Vardy in extra time.
"I think it was a penalty and perhaps another penalty on Vardy," the Frenchman said. "It was a fantastic game but the penalty [shootout] was not for us.
"It's a disappointment but we have no regrets about our play because the players gave their best and it was a competitive game and it's encouraging for the future. Now we have to keep this high level but it's a good response after our last game on Saturday."
Youngster Alexander Zinchenko was unsure if the Foxes' last-gasp penalty should have been given.
"We had to keep going and play the same way because before the penalties we hadn't played too badly, we had controlled the whole game except the last moment,'' he said.
"I don't know if it was a penalty or not but we won it.''
