Ben Yedder's early strike gave Liverpool all to do in their Champions League opener at home to Sevilla.
Klopp's side found the equaliser in the 21st minute, though, through frontman Roberto Firmino.
Alberto Moreno's burst in the box led to a dangerous ball in the middle, and amidst the rush of players was a readied Firmino, applying the final touch.
