Liverpool boss Jurgen Klopp says Saturday's clash with Tottenham will be a good test for his young team.
The Reds will meet their top four rivals in London tomorrow night.
Klopp said, "It is a really tough test. I can't remember an easy game; we played at Newcastle, that was tough. Chelsea too; the away games have all been tough and home games not easy.
"Tottenham is doing really well. Ange [Postecoglou] seems to be a top bloke, I'm looking forward to meeting him. If you saw Celtic play you'd know how good a coach he is. He is delivering good football in a year when Harry Kane left. He is doing extremely well; they are exciting to watch. It'll be a test for both of us."
Klopp also discussed the impressive form of Dominik Szoboszlai: "The boy is impressive; very smart. He is really nice too, close to everyone. He has charisma; he was so happy to come here, which is nice to see. He never played the position he is playing now, but we are learning together. It is a joy to work with him."
