Tottenham defender Toby Alderweireld says Spurs' defensive solidity is the key to their nine-game unbeaten run in the Premier League.

Tottenham have conceded only eight goals so far this season – a vast improvement on last campaign where they allowed more goals than relegated Hull City.

Alderweireld said improved defensive organisation has been the reason for Spurs' success.

"We had only one defeat and that was the first game. We have a good organization and everybody works very hard for the team," Alderweireld told NBC Sports.

"I think up front we can make more of a difference but we are in a good way and we've had a lot of difficult games where we have stood our ground and I think we are a team who are difficult to beat."
