It will be "almost impossible" for Manchester City to win the quadruple this season, Pep Guardiola has said.
His City side beat Brighton 1-0 on Saturday to reach the FA Cup final.
They have already won the Carabao Cup, are in the Champions League quarter-finals and are currently second in the Premier League as they attempt to become the first English club to win all four trophies in one campaign.
"Surviving is a miracle. It's nice to be there," the City manager said.
"Nobody has done it [won the quadruple], so why can we do it? It is almost impossible to achieve everything - that is the truth."
City were below their best against Brighton but Gabriel Jesus' early goal saw them reach the FA Cup final for the first time during Guardiola's reign.
The closest any English club has come to winning all four trophies in a season was Manchester United when they won the Treble - the Champions League, Premier League and FA Cup - in 1998-99. They remain the only side to achieve that feat.
"Do you believe we can play 60 games and give a fantastic performance every time? No team can do that," Guardiola said.
"[Former Manchester United manager] Sir Alex Ferguson won the Treble and not every game was like that. It doesn't work in that way."
City's attention now turns to the Champions League on Tuesday, when they play Tottenham in their quarter-final first leg at Spurs' new stadium.
