Ajax boss Erik ten Hag was furious with his Liverpool counterpart Jurgen Klopp regarding claims about the pitch quality.
The two teams battled it out in the UEFA Champions League group stages.
The Reds emerged with a 1-0 win away from home, but they did not play their best football.
And Klopp blamed the pitch conditions after the game, which Ten Hag did not find amusing.
"Klopp saying the pitch was bad? I don't think the pitch was bad, no," Ten Hag told journalists when Klopp's comments were mentioned to him.
"Let's hope we get a better pitch at Anfield then."
