Mason Mount could feature for Chelsea against Liverpool on Sunday.
Mount limped out of the Champions League defeat by Valencia on Tuesday with a nasty-looking ankle injury after he was caught by a late challenge from Francis Coquelin, but boss Frank Lampard has not ruled out the young midfielder.
N’Golo Kante has recovered from an ankle injury and his general fitness will be assessed.
Callum Hudson-Odoi should return from his Achilles injury next week.
Liverpool goalkeeper Alisson Becker and midfielder Naby Keita have returned to training but are not yet in contention.
Alisson has been absent since sustaining a calf injury 39 minutes into the Reds’ opening league match but has started individual sessions with goalkeeping coach John Achterberg.
Keita, who has not played since the Community Shield because of a groin injury, has rejoined team training but striker Divock Origi (ankle) is unlikely to feature at Stamford Bridge.
Fernandinho is set to continue in central defence for Manchester City as the champions host Watford in the Premier League on Saturday.
The midfielder moved into the back four against Shakhtar Donetsk in midweek after John Stones (thigh) joined Aymeric Laporte (knee) on the sidelines. The pair both face lengthy lay-offs.
City have no fresh injuries following their trip to Ukraine and midfielder Phil Foden should be available again after a stomach virus. Winger Leroy Sane (knee) is also still out.
Watford forward Isaac Success is set for at least a month out with a groin problem.
Defender Craig Cathcart should return to training next week following a thigh injury picked up while on international duty with Northern Ireland.
Club captain Troy Deeney continues his recovery after undergoing knee surgery during August.
Man City provisional squad: Ederson, Bravo, Cancelo, Walker, Fernandinho, Otamendi, Garcia, Zinchenko, Angelino, Mendy, Rodri, Gundogan, De Bruyne, D Silva, B Silva, Foden, Mahrez, Sterling, Aguero, Jesus.
Watford provisional squad: Foster, Dawson, Kiko, Holebas, Kabasele, Cleverley, Doucoure, Hughes, Capoue, Deulofeu, Gray, Gomes, Janmaat, Mariappa, Foulquier, Chalobah, Pereyra, Sarr.
Liverpool manager Jurgen Klopp admits they have to improve the defensive side of their game but says a lack of clean sheets is not down to a more attacking approach.
In five matches this season they have scored 15 goals and conceded five in the Premier League, with just one clean sheet – at Burnley last month – in eight matches in all competitions this season.
At the same stage last season the Reds had scored 11 and conceded just two, having opened the league campaign with three successive clean sheets.
They are, however, better off as they currently have a five-point lead, the biggest the Premier League has seen at this early point of the season, having been second to Manchester City on goal difference this time last year.
What cost them the title in their neck-and-neck race with Pep Guardiola’s side was the number of draws (seven compared to City’s two) but Klopp insists they have not sought to rectify that this time around with a more adventurous approach.
“There is no difference. We didn’t focus more on defensive or offensive things,” he said.
“The goals have been strange. There would have been a second clean sheet at Southampton if we didn’t concede that goal (down to an error by second-choice goalkeeper Adrian) would have been a clean sheet, there could have been clean sheets in other games.
“It’s not exactly as we want but we don’t collect clean sheets, we want to win football games.
“It is still early in the season, we have to improve and develop. But it’s not because we have a different approach to last year.”
Part of the reason for a lack of clean sheets could be attributed to the absence of Alisson Becker.
The first-choice goalkeeper won the golden glove last season for 21 clean sheets but the Brazil international has been absent since sustaining a calf injury 39 minutes into their opening league match.
But Klopp has had some encouraging news on his fitness and that of midfielder Naby Keita, who has been sidelined by a groin problem since the European Super Cup victory over Sunday’s opponents Chelsea on August 14.
“Alisson is making big progress. A proper session yesterday with (goalkeeping coach) John Achterberg,” said the Reds boss.
“Not in team training yet, and we take it day by day. We will see. Too early to say. Medical department will tell me.”
On Keita he added: “Naby Keita is back in training with the team. Today is first time with the team.”
However, striker Divock Origi is unlikely to feature at Stamford Bridge after an ankle injury in last week’s win over Newcastle.
“Div, we have to see day by day, that’s how it was from the first day – how can he deal with the pain and stuff like that,” added the Liverpool boss.
“It is pretty early, so I don’t know exactly what the medical department will tell me (today) about that case.
“I think it’s unlikely but why should I rule him out? But it’s unlikely.”
Injuries to Manchester City defenders John Stones and Aymeric Laporte has left them with just one fit centre-back in Nicolas Otemendi and potentially handed a crucial advantage to Liverpool early in the campaign.
Klopp was asked whether worries about an injury to Virgil Van Dijk, UEFA player of the year and the Reds’ key defensive figure, kept him awake at night.
“Not yet. That is the reason why we have four centre-halves,” said Klopp.
“It is not easy for the in-the-moment number four not playing but if something happens, like last year a couple of things happened and then you end up with one centre-half and a defensive midfielder like against Bayern at home with Fabinho and Joel (Matip) as centre-halves.
“That can happen, it was unlucky, but you cannot think about injuries before you have an injury. We all need luck to be really successful.”
