The Reds are back in Champions League action on Tuesday night, hosting Ajax at Anfield (kick-off 8pm).
Andy Robertson, Curtis Jones, Naby Keita and Alex Oxlade-Chamberlain are all out injured.
“Ajax are in the Champions League and they belong there. Are they the strongest team in the competition? I haven’t seen the rest yet,” said Klopp ahead of the game.
“We have to show a reaction but that doesn’t guarantee a result against Ajax. They’ve won all their games this season, they’ve had a massive rebuild but they’re doing a really good job.
“We have not been consistent enough this season and we have to show that again. And that always starts with defending better.”
