Joel Matip's 89th minute header kickstarted Liverpool's season as a 2-1 win over Ajax at Anfield put the Reds back in the running to reach the last 16 of the Champions League.
Jurgen Klopp's men had won just two of their opening seven games of the season, and suffered a 4-1 thrashing at the hands of Napoli on matchday one.
Last season's Champions League finalists were much more like their old selves but still needed a late winner from an unlikely source after Mohammed Kudus had cancelled out Mohamed Salah's opener.
Victory takes Liverpool level on three points with Ajax and Napoli, who travel to Rangers in the other game in Group A on Wednesday. "If you put the two games next to each other, I don't think you recognise the same squad," Klopp said of his side's improvement from six days ago in southern Italy.
