Suarez scores twice on return

Liverpool broke the deadlock with a controversial goal in the first half as Daniel Sturridge turned the ball in with his arm, before Suarez quickly doubled their lead.

Emanuele Giaccherini reduced Sunderland's arrears on 52 minutes but, despite a spirited performance, Kevin Ball's men could not find an equaliser and Suarez netted again in the closing stages to lift Liverpool to within two points of leaders Arsenal and in second place ahead of Spurs on goals scored.

Jonny Howson's first-half strike steered Norwich to their second Barclays Premier League win of the season as they defeated Stoke 1-0 at the Britannia Stadium.

The Canaries took advantage of sloppy play from their opponents in the 34th minute as Howson collected the ball from Anthony Pilkington and beat Stoke goalkeeper Asmir Begovic, who might have done better, from outside the box.

Norwich had already hit the crossbar through Ryan Bennett and were good value for their lead.

Stoke improved after the interval and looked unlucky not to be awarded a penalty when Leroy Fer had a hand on Kenwyne Jones in the area, before Begovic pulled off a smart save to keep out a Robert Snodgrass shot.
