Christian Benteke condemned struggling Sunderland to a 1-0 defeat and sent Liverpool level on points with sixth-placed Manchester United in the last Premier League game of the year.
The Belgium striker, tightly marked in a goalless first half at the Stadium of Light, burst into action 22 seconds after the restart to bag his sixth goal of the campaign.

Nathaniel Clyne's long and low pass was deflected on by Adam Lallana to the lurking Benteke, who made no mistake in tucking it away from inside the area with Sunderland's defence caught napping.
Liverpool, who beat high-flying Leicester City 1-0 on Saturday with another second-half goal from Benteke, have 30 points from 19 games but Juergen Klopp's side are behind Manchester United on goal difference.
Sunderland remained second from bottom on 12 points after five straight defeats, seven points adrift of safety.
