A welcome boost at West Ham on Tuesday night was the return of playmaker Philippe Coutinho after a month out with a hamstring injury, who scored with a free-kick which went under the wall.
"It was one of the smartest free-kicks in football, you don't see this too often and it was really cool," said Klopp.
"Phil Coutinho is in good shape and I don't know the names of too many teams in the world where he would not play.
"He has had two not too long but long-term injuries where four or five weeks (out) in the middle of the season is not too easy.
"He has to come back and find his rhythm and we will try to help him but if Phil is back he is always someone who can make the difference in a game."
