Burnley restored their lead at the top of the Championship to three points as they deservedly beat a resolute Birmingham City.
World Cup renegades Anass Zaroury and Connor Roberts hit first-half goals, supplemented by an injury-time third from Nathan Tella, as Vincent Kompany's in-form Clarets completed their 14th win in 24 Championship games this season to edge clear again of second-placed Sheffield United.
Against the second meanest defence in the second tier, the hosts got off to a flyer when Zaroury hit the fastest Championship goal of the season - after just 49 seconds.
After helping to set up the first goal, Roberts then got in on the goalscoring act himself when he ended the first half as it had begun a minute before the break with another very neatly worked move down the right.
