Jurgen Klopp said he could not enjoy Liverpool's late win over Leicester after Hamza Choudhury's foul forced Mohamed Salah to hobble off.
The Leicester midfielder scythed down the Liverpool forward to prevent him taking a clear route to goal in the final minute of the game at Anfield, and was given a yellow card, while Salah, after playing on for several minutes, left the pitch in visible pain, with his longer-term condition as yet unknown.
Liverpool went on to keep up their winning streak for a 17th Premier League game but, after the match, a sullen-looking Klopp fumed at Choudhury - whose red-card foul on Matt Ritchie in August left him on the sidelines for two months.
