Meanwhile, it looks like Gabriel Jesus could be back sooner than it was initially reported with the Brazilian taking incredible strides towards his recovery.
The Brazilian has been sidelined since New Year's Eve with a medial ligament injury he picked up at Crystal Palace.
Pep said: "On Friday, he is going to play in part of the session with the group".
Roberto Martinez recalls the moment with such clarity that it is hard to believe five years have passed since Wigan Athletic produced the biggest upset in the FA Cup final for a quarter of a century by beating Manchester City 1-0.
"I don't know when he'll be ready to play - the first step was to make one or two weeks of training alone - but today will be his first training for the team".
Guardiola is pleased with his rapid recovery although he is not yet fully fit.
He said: "It would be good for my players not to think too much of the final next Sunday, they (should) think about the final next Monday". "Without the ball not ideal - he has to be involved with and without the ball - but he can do it, we'll give him the passes".
Challenging for major silverware should help to get him back up to speed for an important run of fixtures which will also see City face Arsenal and Chelsea in the Premier League and Basel in the second leg of the Champions League last 16.
Meanwhile, Guardiola refused to be drawn on criticism from Leicester City boss Claude Puel of his club's pursuit of Riyad Mahrez.
"Of course I am concerned because I saw the game against Bournemouth, they are one of the teams I like to watch the most in the Premier League and they were able to beat them", he said.
City have not responded publicly, but are understood to refute Puel's version of events having first made their interest in Mahrez known a week before deadline day.
Guardiola further added, talking about the Fa Cup "I think the FA Cup there are a lot of surprises, not just this season or previous seasons, all throughout history you always have these kind of situation happen".
