Leaders Leicester City belatedly grasped their golden opportunity to pile the pressure on their Premier League pursuers on Saturday as a late winner from Leonardo Ulloa sunk struggling Norwich City 1-0 at the King Power Stadium, Reuters reported. With closest challengers Tottenham Hotspur and Arsenal not in action until Sunday, Leicester had the stage to themselves to forge five points clear at the summit and made the most of their chance with a victory they scarcely deserved. Despite producing one of their flattest performances of their surreal season, Ulloa's 89th-minute contribution, sliding in to knock home Marc Albrighton's cross, was decisive. It stretched Leicester's advantage to five points over the north London duo although both second-placed Spurs, at home to Swansea City, and third-placed Arsenal, who visit Manchester United, can reduce the deficit again on Sunday. Champions Chelsea fought back with late goals from Cesc Fabregas and Branislav Ivanovic to earn an excellent 2-1 win at Southampton.
