Pochettino said Spurs would face a challenge "to beat a great team like Juventus, to score against a team that has conceded one goal in 16 games".
And yet, Arsenal still could have stolen a point.
Had it not been for Petr Cech's saves, the damage could have been far worse for Arsenal at Wembley. This allowed Arsenal to stay in the match and Wenger threw on three attackers to try to nip an equalizer. Spurs looked likely to increase their lead when ever they got over the half way line but never did.
A man who loves football, attending one of the biggest Premier League fixtures on the calendar - we shouldn't be reading too much into that, surely? Davies was given space to left of the area to swing in an inviting cross, and Kane rose highest to power a header into the bottom-left corner. Moments later, Lacazette found himself in behind the Spurs defense.
Although it was only 1-0, there was a gulf in class between the two rivals.
His importance to the Tottenham side can not be overstated, and after the comfortable victory over Arsenal, Pochettino said of his superstar, as quoted by Marca: "He's the present and future of this club".
Tottenham started using Wembley as their home stadium this season as their old stadium, White Hart Lane, was completely demolished at the end of July 2017.
There is a seven-point gap with Mauricio Pochettino's side moving up into third, leaving Arsenal down in sixth. Kane probably should have had a hat-trick to his name, but as the talisman of this team, his all-round forward play in the second half was superb and was the basis upon which Spurs were able to open up their opponents easily.
Immediately after Kane's goal, which meant Cech has now gone nine Premier League matches without a clean sheet, the longest run of his career, it could've gotten worse quickly for Arsenal. Just about at the death, Lacazette would see this chance go begging.
The chances began flowing for both sides after the goal. Toby Alderwiereld's return to the side in the midweek win over Newport County will be a huge boost to Spurs while Victor Wanyama's availability gives them more solidity at the base of the midfield.
