The City boss, talking to journalists at his Friday press conference, was asked if there were any fresh concerns following the international break, as well as the progress of Ruben Dias and Cole Palmer.
Asked when Dias might be back and whether he could be in contention for our Champions League quarter-final with Atletico Madrid and next weekend’s home clash with Liverpool, Guardiola confirmed the Portuguese is likely to miss out.
“I don’t know how long, the doctor said four to six weeks,” he said.
“Ruben is on week four now, first of March he was injured, four weeks later, I think we need two weeks more.”
Guardiola also says he is only thinking about the Burnley clash and not the Atleti and Liverpool fixtures.
Asked if those games might affect his selection at Turf Moor, he said: “The plan depends on what I saw of the players in training.
“I saw how much they come back, the guys on holiday for one week and come back and after I decide.
“We have to win the game at Burnley.
“We have a lot of games this month and every game will be the best available to select.
“People come back from international break, some less tired than others, people fitter than others.
“It depends on what and the opponent when we do the selection.”
With at least eight games to come in April – and possibly more depending on re-arranged fixtures and Champions League progress – Guardiola says his squad are used to fixture congestion at this time of the campaign.
“It’s not the first time we face it, we’ve done incredibly well so far, we face that because we are in all competitions,” he said.
“Now it’s game by game and next it’s Burnley away which is always tough especially the way they play.
“I have incredible respect for Sean Dyche and the people because for many years, the consistency in ideas and the way they play.
"For me, when you become a good manager, (you are) not depending on the results going good or not and are going to change the way.
"I believe in what we have to do, he believes what they are doing and it works.
"I remember how difficult it is to go there and we will try to go again.
“We can make a mistake and still win the title, nobody knows.
“We will fight until the end, that's for sure.”
