Robert Huth's double and a Riyad Mahrez goal sent Premier League leaders Leicester City six points clear after a stunning 3-1 victory at shell-shocked title rivals Manchester City on Saturday. Leicester produced another exhilarating counter-attacking performance, playing with confidence and swagger in the top-of-the-table clash at the Etihad stadium. Poor marking allowed defender Huth to sweep in Mahrez's free kick, via a deflection off Martin Demichelis, after three minutes. Playmaker Mahrez finished off a swift break to score his 14th league goal of a hugely impressive season and double Leicester's lead three minutes into the second half. Huth headed in a corner on the hour to make it 3-0, proving that Leicester, on 53 points from 25 games, have the quality and belief to make a sustained challenge for a first English top-flight crown. Sergio Aguero headed a late consolation for the hosts.
