Divock Origi and James Milner were on target as Liverpool edged out a stubborn Sunderland side at Anfield.
Divock Origi came off the bench to inspire Liverpool to victory against Sunderland and send Jurgen Klopp's men to the top of the Premier League on Saturday.
Origi, a 34th-minute substitute for the injured Philippe Coutinho, curled home the opener with 15 minutes to go and James Milner added a late penalty to move the Merseyside club back above Manchester City at the summit on goal difference. They can be replaced by Chelsea should Antonio Conte's men beat Tottenham in the late game.
