The Reds go to Burnley on Sunday.
Klopp said: "I had the pleasure to watch Burnley against United. This situation explains the Premier League the best. The quality they produced was incredible. It was a proper team performance. There is a big possibility for them to still stay in the league.
"They brought in a new striker [Wout Weghorst]. If you saw the game, you would have seen he is a lively boy. He was very active all over the pitch. Burnley ask for all physicality you can put in a game, we cannot have the ball all the time and they are good when they have the ball.
"They have footballers everywhere. On top of that, the set-piece threat, we have to be aware and concentrated."
On the meeting at Anfield earlier this season, he added: "It was the best game we played against Burnley since I was here."
