Mohamed Salah opened the scoring for the Reds shortly before the interval after a lightning-fast break, cutting inside expertly before firing into the far corner of the net.
The Egyptian added a second with a superb piece of improvisation from close range in stoppage time at the end of the match to round off an eighth-successive victory for the home side.
Sadio Mane thought he had headed Liverpool two up early in the second half, but VAR ruled that he was fractionally offside, much to the frustration of the home supporters.
Wijnaldum sat down holding his hamstring moments later, with Jurgen Klopp bringing on Andrew Robertson in his stead for the final portion of the game.
The Netherlands international received treatment on the pitch initially, before limping over to the touchline in considerable discomfort.
