The Football Association has appealed against the decision to only fine Liverpool manager Jurgen Klopp for confronting the referee in his side's match against Manchester City last month.
The German escaped a touchline ban but was fined £30,000 by an independent regulatory commission on October 27 over his conduct towards officials during the game on October 16.
The FA has now reviewed the commission's written reasons and is understood to feel the sanction imposed was too lenient.
The German lost his cool with assistant referee Gary Beswick during the game at Anfield
Klopp lost his cool in the game when assistant referee Gary Beswick failed to give his side a free kick after Bernardo Silva appeared to drag down Mo Salah, shouting in Beswick's ear as the game continued.
