The centre-back is scheduled to go to Belgrade for treatment on the hamstring injury he suffered against Stoke City on Tuesday, which rules him out of tonight’s FA Cup tie with Exeter City and next week’s high-profile Premier League games with Arsenal and Manchester United.

Among Kovacevic’s methods is the use of fluids derived from horse placenta which are massaged onto the problem area and which she claims cuts short the healing process.

The Anfield club is in the midst of an injury epidemic with 12 players out for the Exeter game and manager Jurgen Klopp targeting his former club, Borussia Dortmund, for defensive reinforcements with Neven Subotic of interest.
