Leicester City was left in touching distance of a fairytale first Premier League title Sunday after Leonardo Ulloa's double helped it outclass Swansea City 4-0 at a delirious King Power Stadium. The Foxes' dream of completing its surreal journey from no-hopers to English champion felt more tantalizingly real after 10 minutes when Ashley Williams' careless clearance gifted Riyad Mahrez his 17th goal of the season. Then Ulloa, filling in for Leicester's suspended top scorer Jamie Vardy, took center stage. He headed home the second on the half-hour and tapped in a third on the hour as the Foxes cruised while their fans merrily sang: "Are you watching, Tottenham?" The Spurs faithful who were watching could only sigh as substitute Marc Albrighton smashed in a fourth in the dying minutes to confirm Leicester's eight-point lead over the second-placed Londoners. Should Tottenham lose its game in hand at home to West Bromwich Albion Monday, the Foxes, who need five points from their last three games to take the title, could even be crowned champions next Sunday with victory at Manchester United. Earlier, Sunderland moved out of the relegation zone as Arsenal stumbled again in a 0-0 draw in the English Premier League. A game full of chances saw Sunderland's Patrick van Aanholt rattle the woodwork with a first-half free kick while at the other end former Arsenal keeper Vito Mannone made several great saves to deny his old club. Both sides had strong penalty appeals turned down too, first when Arsenal defender Per Mertesacker blocked Jermain Defoe's shot with his arm, then minutes later when DeAndre Yedlin's outstretched arm deflected away Alex Iwobi's shot. Arsenal finished strongly and Mannone saved from Alexis Sanchez and Danny Welbeck but Sunderland grasped the point that moved it above Norwich City on goal difference with both sides having four matches to play. Second-from-bottom Newcastle United is a point back with one less game remaining. "We've got ourselves out of the bottom three now for the first time in many months and the challenge now for the lads is to stay out of it," manager Sam Allardyce said. "I thought we definitely should have had a penalty. Mertesacker turned his back on the ball with his arms in the air and stopped what looked like a certain goal." Arsenal stayed in fourth spot, behind Manchester City on goal difference and five points above FA Cup finalist Manchester United, but a 19th consecutive appearance in the Champions League is still not guaranteed as United has a game in hand. — Agencies
