Liverpool legend Jamie Carragher believes Sadio Mane's frustration with teammate Mohamed Salah would have been building for some months.
Mane cut an angry figure when he failed to receive a pass from Salah in the closing stages of last month's 3-0 win over the Clarets at Turf Moor.
The forward was substituted soon afterwards, and was seen shouted at several figures on the Liverpool bench including club captain Jordan Henderson, while James Milner was seen trying to calm his down.
Reds manager Jurgen Klopp played down the incident after the match, and Salah in particular has been at pains to laugh it off.
Carragher wrote for the Telegraph: "There is no way Mane lost his head solely because he did not receive a few passes against Burnley . His frustration will have been gathering for months, ensuring it only needed a trigger to bring it into the open.
"Jurgen Klopp is not a manager who allows his players to dwell on any negative issue so I strongly suspect he will have discussed it with both players.
"Ironically, I felt Mane was too unselfish in the Champions League game against Napoli in midweek, trying to pass to Salah when he should have been going alone.
"So long as these disagreements are isolated and issues swiftly resolved they do not cause a problem.
"Where managers do become wary is if cliques form, sides are taken and personalities clash to such an extreme it becomes detrimental to the unity and spirit within the camp."
