Borussia Dortmund boss Jurgen Klopp was impressed by Liverpool on Saturday.
The Reds routed BVB 4-0 at Anfield.
Asked about Luis Suarez's departure, Klopp said: "It seems to be no problem! They have a plan maybe but I don't know. We can play better than that and Liverpool can play better too.
"Liverpool is a great club and they did well last year. I saw it. If you make the right decisions after you miss (a trophy) you can be stronger. Maybe Liverpool this year is the big team in the Premier League. We will see.
"We are only the middle of our preparations and on Wednesday we have the other match against Bayern Munich in the Super Cup. Our problem at the moment is not (missing) Lewandowski. The players all start at different moments and this was not the ideal time to face Liverpool."
