LIVERPOOL - Champions Liverpool suffered a shock 1-0 defeat to lowly Burnley on Thursday, ending their 68 match unbeaten home record in the Premier League as their title defense continued to fade.

An 83rd minute penalty from Ashley Barnes, after he was brought down by goalkeeper Alisson Becker, decided the contest after Juergen Klopp’s side failed to score for the fourth straight league match.

Matt Lowton nodded a header into the box and Barnes wriggled free of Fabinho and went down under challenge from Becker, rising to confidently convert from the spot.
