For Tottenham, a first away win since September to displace Burnley from the top six and restore a familiar hierarchy up there. But it took a dubious stroke of fortune to get them under way before Harry Kane delivered a familiar performance of quite outstanding class. The rancour stretched from the stands to the Tottenham dug-out as the night wore on and Mauricio Pochettino's coaching staff were clearly agitated by two individuals making their feelings felt in the Burnley corporate seats. The source of it all was the penalty – won by Dele Ali, converted by Kane – which proved to be pivotal.
