Tottenham boss Jose Mourinho says there's still room for improvement after their 5-0 rout of Burnley.

Harry Kane's brace and further goals from Heung-Mon Son, Lucas Moura and Moussa Sissoko continued Mourinho's honeymoon period in north London.

And it was a clear sign of Mourinho's pleasure that the first thing he mentioned in his post-match interview in the tunnel was the clean sheet.

"There are still a few holes and chances to opponents but we were much, much, much more solid," he said.

"It's the best day because it is the complete performance. It was perfect."
