Liverpool are reportedly sweating over the fitness of Mohamed Salah, Andrew Robertson and Georginio Wijnaldum ahead of their return to Premier League action.
The Reds' title charge resumes with a Merseyside derby clash against Everton on June 21, with Jurgen Klopp's men potentially just one win away from sealing top spot.
However, Liverpool may be without a trio of key players for their first game back as The Express reports that Salah, Robertson and Wijnaldum sat out their latest training match.
Back-up goalkeeper Adrian was also absent for the internal game, though Liverpool still have a friendly against Blackburn Rovers to come later this week, giving each player another chance to prove their fitness.
Klopp's side hold a 25-point lead over Manchester City at the top of the Premier League with nine matches to play.
