The City playmaker has been superb for much of the season and is now arguably playing the best football of his career.
His match-winning goal against Bournemouth was his fifth of the month and he was again outstanding throughout another difficult test on the road.
Asked if Foden’s goal contributions were important, Guardiola said: “Forget about the goals - of course they are important - but do you know how he played?
“How he controlled and accelerated. He has become already a top class football player.
“From a little boy, now he has become already Phil, a world class, top player.
“He’s so good. He can play everywhere, especially in the central position and play really, really good.”
The boss also says he has nothing but admiration for his entire squad.
Once again, the Blues were pushed hard by a team lower in the table, but Guardiola says his players keep delivering, year after year – and even he is amazed by their consistency and performance levels.
“So, what can I say? The calendar is so demanding and the expectations are so high,” he said.
“What they have done for many years with a lot of games and many things.
“And always you believe they will fall down and won’t continue to do it - they surprise me.
“Because I tell them ‘it’s not normal’. For many years we are three days every game.
“Bournemouth had seven days to prepare one game. Seven days dreaming every second the one week to be the best team in the world.
“And we have three days to prepare that. The people say we play the same conditions.
“We are not playing the same conditions. In the Premier League we are playing the same conditions. It’s a lot of competitions, I love it, I like it.
“Still they are there, I don’t know how much longer we arrive in the competitions, but we are there.
“Knowing where we come from, it’s unbelievable.”
