Daniel Sturridge may return for Liverpool against Manchester City

Liverpool manager Jurgen Klopp has not ruled out Daniel Sturridge for Saturday's trip to Manchester City — but he insists the striker has to put in more hours on the training ground to prove his long-term fitness.

The 26-year-old has played just 242 minutes across three matches this season after recovering from hip surgery which ruled him out of the final six weeks of the previous campaign.

He has not featured since playing 90 minutes in the Merseyside derby at Goodison Park — Brendan Rodgers’ last match in charge — in October after a collision with Jordon Ibe in training sidelined him with a knee problem.

Sturridge rejoined the full squad for training on Tuesday but Klopp has still not decided whether to include him.

“He is as fit as he can be after a long break. Of course he is not at 100 per cent and of course we have to see,” said Klopp.

“Today was the third full exercise with the team after four and a half, five weeks’ break — I’m not sure Liverpool had that long a break in the summer.

“For four and a half weeks he has not trained; not cycling, running, not, not, not.

“But because he is that skilled a guy maybe we should.....(include him at the weekend).

“As a striker sometimes five minutes are enough and I have to decide this tomorrow.

“I don’t know what I will do when I build the squad, I have to think about it.

“Everyone wants to see more of him on the pitch so you have to train but we have to find the right balance.”

Sturridge’s issue has never been his ability — scoring 42 goals in 72 matches for the club — but his ability to stay fit.

The surgery he had in May was designed to clear up previous longer-term issues with calf and thigh and his latest injury was purely accidental, although his recovery took longer than anticipated.

Klopp now just wants to see the striker put the hours in on the training ground at Melwood to ensure he is ready for the challenge which lies ahead in the remaining six months of the season.

“His quality is outstanding, we don’t have to talk about this, but everyone needs training,” he added.

“The problem with Daniel’s quality is that everyone can see it, it is obvious and he is an unbelievably strong player.

“We have to think about him but, for example, we can take him to Manchester and he can train around the game.

“He has to train now, that is for sure.”

Meanwhile, Sergio Aguero hopes to return for Saturday’s match.

The prolific Argentina striker has missed City’s last seven games after suffering a hamstring injury while on international duty.

A comeback for the 27-year-old — who scored five goals against Newcastle on his last City appearance — would be timely with fellow forward Wilfried Bony doubtful with a hamstring problem.

Aguero told the club’s website, www.mcfc.co.uk: “I do hope I can play in this game. I’m doing everything in my power to get to the match in top condition. It’s been a frustrating time.”

Ivory Coast international Bony was sidelined during the recent international break after being forced off early during City’s goalless draw at Aston Villa on November 8.

Playmaker David Silva could also be nearing a return after a seven-game absence with a knee injury but Samir Nasri looks set to be out until February with a hamstring problem.

Saturday’s encounter against Jurgen Klopp’s Liverpool at the Etihad Stadium will see City come up against their former midfielder James Milner, who left the club for Anfield in the summer.

Aguero said: “He’s a great player, though it will be odd to see him wearing another team’s colours.

“He is a true professional and I’m sure he’s going to come against us with everything he’s got.

“It should be a great game. Jurgen Klopp has come in and he’s a great addition to the Premier League.”
