Tottenham Hotspur have now kept three clean-sheets in as many matches.
Spurs have kept three clean-sheets in as many matches, and Pochettino is pleased to see his side looking so secure.
The Argentine boss believes that he has a lot of options in defensive areas, and he says that the strength of his back-four highlights the quality which he wants to have flowing throughout the squad in the future.
"I think it's the strongest defence I've had at the club so far," he said. "I'm very happy. This is the way that we want to play. We want to be a strong team for the future."
Tottenham recruited well in defensive positions over the summer, making a number of additions to ensure that they tightened up their backline.
Spurs were particularly porous towards the backend of last season, but they appear to have made themselves much harder to beat - and have not tasted defeat since an opening day loss to Manchester United.
The addition of Toby Alderweireld at centre-back has been an astute one, while the likes of Kieran Trippier and Kevin Wimmer have added further strength in depth.
Spurs are now in ninth position in the Premier League table, and have conceded just four goals in their opening six matches.
