A shin injury has kept Grealish out of City’s last three games, whilst Jesus has not featured since the 1-1 draw with Southampton last month after returning from international duty with a knock.
Pep Guardiola has been pleased with what he's seen from both players in training this week and says it is important to have them back in contention.
“They are ready,” he said at his pre-match press conference. “It’s so important for us, definitely.
“He [Gabriel] is so important in the first press. He is so unpredictable in the final third.
“He was out for two or three weeks, Jack as well, but they are back and how they move in these days was good.”
City travel to Everton looking to bounce back from last weekend’s defeat to Tottenham Hotspur, whilst the home side will be aiming to secure a result which puts distance between themselves and the relegation zone.
The Toffees are two points clear of 18th placed Burnley heading into Saturday’s contest, but have won both of their home games under new boss Frank Lampard.
Guardiola acknowledges his side are in for a difficult test on Merseyside, but remains confident we can take all three points.
“Everyone in the world would think they wouldn't be in that position,” added the boss.
“I'm not there to know the reason why.
“They have good players, they are fighting for being where they should be from the history.
“It will be tough at Goodison Park, but I have full confidence in these players.”
