Luis Suarez marked his return to Premier League action with two goals to help Liverpool to a 3-1 win at managerless Sunderland that lifted them to second in the table on Sunday.
.
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 being suspended for biting Chelsea's Branislav Ivanovic in April.
.
He scored Liverpool's second in the 36th minute after Daniel Sturridge had opened their account eight minutes earlier with a controversial goal that went in off his upper arm after he had risen to try to head in a corner.
.
Sunderland, bottom of the table with one point, got themselves back into the game early in the second half when Emanuele Giaccherini pounced after keeper Simon Mignolet failed to deal with Ki Sung- yeung's long-range effort.
.
Suarez had to wait until the 89th minute for his second goal and it was Sturridge again who set him up for a simple finish that sealed Liverpool's fourth league victory of the season.
