Liverpool boss admits Brazilian is still off the pace.
Coutinho managed 18 touches and created one chance as the Reds drew their Champions League opener 2-2.
Klopp admits Coutinho is still working his way back to match sharpness, and was below par.
He said: "Phil trained in the last few days really, really well but tonight and tonight a few situations were not too lucky and he was without rhythm.
"But it helped him he could play tonight and it helped us in the long term, for sure, so all OK."
Liverpool were pegged back by Sevilla after going a goal down after just five minutes.
Strikes from Roberto Firmino and Mohamed Salah had put them in front before Joaquin Correa scored a late equaliser for the La Liga side.
The positive for Liverpool was that the other game between Maribor and Spartak Moscow also ended in a draw.
