Daniel Sturridge will undergo another scan on his knee as he emerged as a major doubt for Liverpool’s clash against Southampton on Sunday.

Manager Jurgen Klopp revealed there is “fluid” in Sturridge’s knee following the damage caused by  a training ground collision with Jordon Ibe last Friday.

However Klopp has not ruled Sturridge, who did not line up against either Tottenham Hotspur or Rubin Kazan, out of Sunday’s match.

“I spoke to him and the situation isn’t much better,” said Klopp at his media briefing on Friday. “With his injury, we have to see day by day. If he can train, for example, tomorrow – if – completely normal, then he is an option because his break has not been too long.

“But I have to wait for this. Today there is another treatment. There is a little bit of fluid. Another scan. It’s day-by day.”

Klopp’s comments about the latest Sturridge injury will heighten anxieties among Liverpool supporters, who have hardly seen the 26-year-old play in the last 12 months due to a succession of ailments from a torn thigh muscle to hip surgery.

It has been a chastening introduction to English football for Klopp as he lost Danny Ings, Liverpool’s top scorer for the season, with a ruptured anterior cruciate ligament in his third training session, while Joe Gomez will also miss the rest of the campaign with a knee injury sustained on England Under-21s duty.

However, Christian Benteke has returned from a hamstring injury and played 25 minutes against Rubin Kazan, while Roberto Firmino also played for the first time in that 1-1 draw since September 24.

“If all the strikers are fit we have to think how we can use their quality,” said Klopp. “I don’t know if we will use two strikers on Sunday but in the future for sure it is an option. Christian was unlucky with the post, Roberto did well. They are two very important options.”
