Former Liverpool fullback Stephen Warnock was hugely impressed by Atalanta last night.
La Dea won 3-0 at Anfield in the first-leg of their Europa League quarterfinal.
Warnock told BBC Sport: "[Atalanta] dominated Liverpool. They created so many chances. Liverpool were poor. They were arguably the worst I have ever seen them [under Jurgen Klopp].
"Wasteful in possession. So many mistakes all over the pitch but they looked tired. They looked like a team that has played 56 games in a season and you could just see tired minds and tired bodies. But take nothing away from Atalanta. They were magnificent.
"It was one of the best opposition performances I have seen at Anfield. I have been to some European nights and seen Liverpool outdone by opposition teams. That was hugely impressive.
"To come here and play the way they did and take the game to them, it's outstanding."
