Premier League leaders Leicester City stunned nearest rivals Manchester City with a convincing victory at Etihad Stadium to move five points clear.

Robert Huth met Riyad Mahrez's free-kick to give the Foxes an early lead. City rarely looked like breaking down the visitors' defence, while their own back line appeared vulnerable.

Mahrez made it 2-0 with a step-over and finish, and Huth found space to head home a Christian Fuchs corner before Sergio Aguero's late consolation.

Claudio Ranieri's side travel to fourth-placed Arsenal next weekend - win there too, and people might be asking 'who can catch Leicester?' rather than 'can the Foxes really win the title?'.

Thousands of Liverpool fans walked out of Anfield in protest at ticket prices as struggling Sunderland came from 2-0 down to secure a crucial point.

Roberto Firmino headed the Reds in front after James Milner's clever cross before the goalscorer turned provider to allow Adam Lallana to tap home.

Fans were pouring out when Reds goalkeeper Simon Mignolet was beaten by Adam Johnson's curling free-kick at his near post. Jermain Defoe completed the comeback after finishing from 10 yards.

Liverpool had striker Daniel Sturridge back on the substitutes bench after a damaged hamstring, but lost defender Dejan Lovren and midfielder Joe Allen to injury in the first half.

The Reds now turn their attention to their FA Cup fourth round replay with West Ham on Wednesday morning, while Sunderland host Manchester United next Saturday night, looking to get out of the drop zone.

Southampton earned their fourth win in five matches, despite a third red card of the season for midfielder Victor Wanyama.

Saints started strongly and took the lead when Maya Yoshida smashed home Saido Mane's cross before Wanyama received a straight red card from referee Mark Clattenburg for diving in on West Ham midfielder Dimitri Payet.

The hosts survived a late scare when defender Cedric sliced a clearance narrowly past his own post, however the Saints held on and the victory lifts them to seventh in the table, just one place and two points behind West Ham.
