Manchester City kept their hopes alive of winning the quadruple this season as they overcame Newport County 4-1 at Rodney Parade in the FA Cup.
It certainly wasn’t a comfortable evening for the Premier League champions with the League Two side holding out until half-time.
However, City’s quality soon told and goals from Leroy Sane, a brace from Phil Foden and Riyad Mahrez sealed passage into the quarter-finals.
Their attention will now turn to the Champions League, where they travel to Germany to face Schalke on Wednesday.
City will certainly be looking to do better than their Manchester rival in the competition.
Manchester United hosted Paris Saint-Germain in their first leg but lost 2-0, despite the French side having both Neymar and Edinson Cavani missing.
And Guardiola couldn’t resist having a dig at United and accused them of ‘believing they are better than anyone.’
"We are in four competitions - every game is completely different. You play League Two then Champions League,” Guardiola said.
"You have to adapt and change mentality and that means a lot to grow like as a team and the big mistake is believing you are better than anyone.
"It is a mistake, like United are praised and 'better than PSG', but you see what happened. You have to be calm and prepare well.”
Under Ole Gunnar Solskjaer, United had been comfortably beating sides by playing free-flowing attacking football.
And Guardiola is seemingly accusing them of trying to do the same against the qualities of PSG - a tactic which backfired massively.
Meanwhile, Guardiola’s side are now top of the Premier League - although they’ve played a game more than Liverpool - in the FA Cup quarter-finals, face Chelsea in the Carabao Cup final and are in the last-16 of the Champions League.
But the Spanish boss is just taking one game at a time at the moment and isn't prepared to talk about a potential quadruple.
"We will see in May and June how we do but it is important to be there in all competitions in February," Guardiola told BBC Sport.
"The result will be shown at the end and now we have to recover and prepare for our trip to Germany [to face Schalke in the Champions League]."News Now - Sport News
