European champions beat Eibar to close in on leaders Barcelona who are held by Sevilla.
Aaron Ramsey maintained Arsenal’s late-season charge by clinching a 1-0 win at relegation-threatened Burnley, an eighth successive victory that keeps the team’s faint title hopes alive.
No other team has enjoyed such a winning run in the league this season, but earlier inconsistency has proved costly for Arsene Wenger’s title ambitions.
Although the Gunners are second – four points behind Chelsea – the leaders have two games in hand on their London rivals.
Securing the win at chilly Turf Moor was hard work for Arsenal, with the tenacious hosts a constant threat after Ramsey’s 12th-minute strike through a congested penalty area.
Burnley is in the drop zone, two points from safety, but has beaten Manchester City and held Tottenham here in the last month.
