Manchester City head coach Pep Guardiola told his players to “conveniently forget” about winning the triple this season.
Manchester City has already won the Carabao Cup and with a win at home in Cardiff on Wednesday can move them to the top of the table.
They are going to face Brighton on Saturday in the semifinals of the FA Cup and Tottenham on 9 April in the first leg of their quarter-finals of the Champions League.
“In one week or three days we can lose all three titles,” Guardiola said.
Since joining City in the summer of 2016, the former Barcelona coach has won two League Cups and the Premier League last season. He keeps playing down the chances of winning all four trophies this season: “I have said many times, ask me at the end of April.
“Why talk about the quadruple when in this country – a legendary country – it has never happened before.
“Legendary teams like Liverpool, the period [of Manchester United] with Sir Alex Ferguson, Jose Mourinho at Chelsea, Arsene Wenger with Arsenal – no one did it. So why should we do it?
“I’m not in the minds of my players and the fans to tell them what to think.
“If they want to dream and think about winning everything, I’m not a guy to say anything.
“Of course we are there but I said to the players, ‘Forget about it, don’t think too much. In one week or three days, we can lose all three titles, that’s the reality’.
“‘I know in your heads we can win all the titles, but for now it’s Cardiff.”
