Petr Cech and the crossbar denied Sunderland a priceless Barclays Premier League victory, as Arsenal failed to reclaim third place from Manchester City.
The Gunners needed to win at the Stadium of Light to edge ahead of City once again, but had to make do with a point from a 0-0 draw which lifted the Black Cats out of the relegation zone on goal difference.
However, they could have left Wearside empty-handed as Patrick van Aanholt hit the woodwork with a first-half free-kick and Cech made a series of important saves after the break to keep Sam Allardyce’s men at bay in front of a crowd of 45,420.
4-0 - Today's result was Leicester's biggest margin of victory in the Premier League this season. Depth.— OptaJoe (@OptaJoe) April 24, 2016
In Sunday’s other Premier League match, Leonardo Ulloa deputised seamlessly for Jamie Vardy in a 4-0 victory over Swansea City on Sunday that took Leicester City to within five points of the Premier League title.
Vardy’s suspension, after he was shown a second yellow card for diving against West Ham United, robbed Leicester of their top scorer, but Argentine striker Ulloa proved a capable deputy by scoring twice as Claudio Ranieri’s men moved eight points clear of Tottenham Hotspur.
Tottenham have a game in hand, at home to West Bromwich Albion on Monday, but Leicester, for whom Riyad Mahrez and Marc Albrighton also found the net, are now almost within touching distance of a title success the like of which world football has rarely seen.
