"Because to make Wembley home and to change the perception from the fans and feel in the end that Wembley can help us to be better and achieve our dream is a big, big job".
"He is very young", Pochettino said.
Paul Dummett was much-maligned the last time Newcastle United were in the top-flight with supporters openly questioning whether he has what it takes to be a starting left back in the top-tier.
It is always going to be tight in the top six and not one of the teams is guaranteed to finish in the top four, let alone win the league title. They played four European matches at Wembley and won only one of them.
But behind those encouraging numbers is the fact that neither Leicester City nor Chelsea were unduly troubled by the north Londoners' challenge on their way to glory, and this season Pochettino will be desperate to mount a real title challenge in spite of a disappointing transfer window so far.
Whether or not that can be fixed this season, seeing Spurs challenge on all fronts and not collapse in one area, will largely depend on keeping Harry Kane fit.
Right-back is a particular priority for Spurs, who will be without Kieran Trippier for the first two weeks of the season.
There have been reports that are linking Spurs to Everton's Ross Barkley. Now, everyone knows, we have to go to Wembley and play. He was injured at the start of the season and Tottenham made a slow start.
Dier is an essential member of the Spurs squad owing to his versatility but he hasn't played at right back for the club since the 2014/15 season and his lack of pace could be exposed by the speedy Christian Atsu out wide. We will find the right players to challenge. It puts Eriksen and Alli as close to Kane as possible and allows them to exploit the space in central areas.
Tottenham Hotspur, who have become rather accustomed to playing the opening game of a new season away from home, will start their Premier League campaign off at newly-promoted (again) Newcastle United.
The 27-year-old understands that the clock is ticking and that, more importantly, Spurs don't come across as a club capable of claiming silverware.
Spurs may not have Cristiano Ronaldo or Sir Alex Ferguson, but there is plenty about them to suggest that for them too, less is definitely more.
The trip to Tyneside revives painful memories of Tottenham's last visit when they lost 5-1 to an already-relegated Toon side 15 months ago.
