Mohamed Salah was "out of order" for arguing with Liverpool boss Jurgen Klopp on the touchline during Saturday's 2-2 draw at West Ham United, says former Premier League striker Chris Sutton.
Salah had been dropped for the game and clashed with Klopp as he prepared to come on as a 79th-minute substitute.
The draw leaves Liverpool, who are out of the Europa League, five points behind Premier League leaders Manchester City.
Sutton felt the incident did not reflect well on the 31-year-old, who is the Reds' top scorer this season with 24 goals but has not been at his best in recent games.
