Luis Suarez marked his return to English Premier League football action with two goals to help Liverpool to a 3-1 win at managerless Sunderland that lifted them to second in the table.
The Uruguay striker, who returned from a 10-match ban for biting in the midweek League Cup loss at Manchester United, was making his first league appearance since April.
Sunderland, who sacked Italian manager Paolo Di Canio last weekend, are bottom of the table with just one point.
Norwich also won 1-0 at Stoke.
Arsenal top the table with 15 points, while Liverpool and Tottenham have 13 - the Reds second on goal difference from Spurs.
