Luis Suarez crowned his English Premier League return with a brace as Liverpool won 3-1 at bottom club Sunderland on Sunday to climb to second place in the table.
Suarez scored in each half at the Stadium of Light as Liverpool ended a run of three games without victory. Daniel Sturridge had given Liverpool the lead with his fifth goal of the season, with Emanuele Giaccherini replying for Sunderland early in the second half after Suarez had made it 2-0.
It was Sunderland's first league game since the dismissal of manager Paolo Di Canio, but although they are now four points from safety, interim coach Kevin Ball will have been heartened by their second-half reaction.
Both sides threatened from early set-pieces, Keiren Westwood denying Liverpool captain Steven Gerrard and Sebastian Larsson rattling the visitors' bar, before the away side went ahead in contentious circumstances in the 28th minute.
A left-wing corner found Sturridge unmarked at the back post and although he shaped to head the ball, it appeared to strike his upper arm before bouncing over the line.
Sunderland's defenders did not appeal, however, and eight minutes later Sturridge's teasing low cross from the right allowed Suarez to slide home his first goal since completing his suspension. The Uruguayan celebrated by lifting his jersey to reveal a T-shirt bearing a picture of his family with his new-born son Benjamin, who was born on Thursday.
The hosts were quick to react though, and after former Sunderland goalkeeper Simon Mignolet had saved with his feet from Craig Gardner and Adam Johnson had shot narrowly over, they drew level in the 52nd minute.
Mignolet could only parry a low drive by Ki Sung-yueng and Giaccherini swept the loose ball home with his left foot to reduce the arrears.
There were chances for both teams, Mignolet denying Gardner again, while Westwood saved from Victor Moses and Kolo Toure, before Suarez tucked in his second goal from another Sturridge cross in the 89th minute.
Earlier, Norwich City won 1-0 against Stoke City at the Britannia Stadium to register their second victory of the league season and only their second away win of 2013.
Stoke manager Mark Hughes has been praised for introducing a more possession-oriented approach since succeeding Tony Pulis in the close season, but his side produced a strangely subdued display.
Jonathan Howson claimed the game's only goal in the 34th minute with a low drive from 25 yards that dipped right in front of Stoke goalkeeper Asmir Begovic.
The two teams now have identical records after seven games of the season and sit three points above the relegation places.
