Liverpool needed two goals in the final 15 minutes to see off Sunderland on Saturday with goals from Divock Origi and James Milner.
Divock Origi felt Liverpool's patience was rewarded as they left it late to beat Sunderland at Anfield.
The Belgium international, a first-half substitute for the injured Philippe Coutinho, curled home the opener with 15 minutes to go before James Milner added an injury-time second from the penalty spot.
Sunderland battled hard but Liverpool fully merited the win to move back above Manchester City at the Premier League summit on goal difference. Chelsea can leapfrog them both with victory in the late game against Tottenham.
