Liverpool boss Jurgen Klopp expects a major battle at Aston Villa on Monday.
Villa are battling for a top four finish.
Klopp said: "It's the last home game of the season for Aston Villa. They want to have a good last home game because they have had an incredible season. They have qualified, pretty likely, for the Champions League, which is a big one. This year Conference League, next year Champions League. An incredible job, but we will give it a try there definitely."
On Villa manager Unai Emery, he said: "Incredible job. Unai Emery is one of the best we have in the business, 100 percent, Wherever he is, success, sometimes the clubs were not ready to wait for it maybe. If you look back maybe these clubs would have made different decisions.
"I've known him for so long. I think when I met him for the first time he was managing in Moscow, if I'm right. That's really long ago.
"He always had a clear idea. It was really tricky for us when we faced him with Villarreal. Always organised the team extremely well.
"The job he is doing is absolutely exceptional and we know how important it is for a club to qualify for the Champions League, how difficult it is for a club to qualify for the Champions League. He probably, very likely, will do that - it's absolutely exceptional."
