Liverpool are sweating over the availability of Emre Can as his ongoing trouble with a back problem could force him out of their Champions League quarter-final first leg against Manchester City.
The midfielder is yet to return to Liverpool training after sitting out Saturday's 2-1 victory at Crystal Palace.
According to The Times, Can spent Monday's training session away from his team-mates as he received treatment on his troubled back and could be a huge blow for Jurgen Klopp should he not make a rapid recovery.
The 24-year-old will be missed by Liverpool on Wednesday night having influenced their recent 4-3 victory over Wednesday's opponents earlier this year and has featured in all-but one of their Champions League matches this season.
