Leicester City eked out a critical win against struggling Norwich City with a late, late winner from Leonardo Ulloa that saw them open up a five-point lead at the top of the Premier League.

Following their crushing stoppage time defeat at Arsenal last time out, the Foxes were, according to manager Claudio Ranieri, "ready for the fight" but for most of the match seemed curiously becalmed as Norwich had the best opportunities.

Cameron Jerome squandered an outstanding chance for the Canaries just before halftime, glancing a header just wide, but though producing one of their flattest performances of the season, Leicester sent the King Power Stadium wild in the dying seconds.

Argentine Ulloa proved the home fans' hero, sliding in at the back post in the 89th minute to latch on to Marc Albrighton's cross and earn the result which leaves Norwich still in peril just above the relegation zone.

Meanwhile, Cesc Fabregas and Branislav Ivanovic struck late goals to earn Chelsea a 2-1 victory at Southampton in the Premier League.

Shane Long took advantage of a mistake by Baba Rahman to put the hosts ahead just before halftime, pouncing on the ball before beating Thibaut Courtois with a neat finish.

Chelsea struggled to create clearcut chances before Fabregas equalised after 75 minutes when the Spanish midfielder's hopeful cross deceived Southampton keeper Fraser Forster and sneaked in at the far post.

It was the first goal the Saints had conceded in seven league games and Chelsea grabbed the winner one minute from time thanks to a powerful header from Ivanovic.
