It was almost a complete performance from Spurs at the Emirates. The combination of Dele Alli, Eric Dier and Moussa Dembele in midfield was too powerful and too quick for Arsenal to deal with. But the person who deserves the most credit is Pochettino.

Spurs have always been a pressing side under the Argentine, but I don't think I've ever seen them press so high up the pitch, even at home. I've also never seen the Gunners dominated like that at the Emirates. Not only did they not have a kick, they almost looked scared. They seemed shocked by how fit and strong Spurs were all over the park, and it's a testament to Tottenham's training. Pochettino's methods are really kicking in. Like Arsenal, Spurs had three games in seven days, including playing on Monday and Thursday, but they were by far the fitter side.

That's due to a combination of having youth in the side and Pochettino's tough training regime. A lot of the players are starting to feel the benefits of it. Kyle Walker, for example, was outstanding against Arsenal - he was an animal - and he's looking every bit England's best right-back at the moment. Dele Alli, a 19-year-old playing in a fierce north London derby, looked like he was playing in his back garden. Even Erik Lamela was running and harrying non-stop - he won more tackles for Spurs than any player on the pitch.

Tottenham's training would have been light during the actual week, because they played so many games, but everything leading up to it has prepared them for weeks like this - all the way back to pre-season. It will be the same over Christmas. And when you have young lads, as Tottenham do, by training hard they become conditioned to playing without even thinking about tiredness. Some of Tottenham's players are young enough that they won't even need to warm up before training. When you have a spring in your step like that, it's a huge advantage when the games come thick and fast. Compare that to someone like Per Mertesacker, who is coming to the end of his career, and playing against Bayern Munich in the week clearly had an effect on him.

Tottenham's key player for me is Christian Eriksen. For Spurs to really mount a challenge they need him to stay fit. He has given them creativity since coming back into the side. Other teams fear him and his delivery is on the money every time. He could add a few more goals to his game, but he's the one who can take them to that next level in the way that Luka Modric did when I was at Spurs.

That team was set up very differently, with speed down the wings, and I think our team would have given this one a very good game, but I think this Spurs side is built to go further in European competition. It doesn't have players of the stature of Modric, Gareth Bale and Rafael van der Vaart, but Bale and Modric blossomed and became those players by virtue of playing in the Champions League. Players like Eriksen and Harry Kane can also grow by playing in Europe’s top competition.

As for Arsenal, they had a terrible week and that was partly due to injuries. Their entire right side of Hector Bellerin and Aaron Ramsey was missing against Spurs. Ramsey was a particularly big miss as he's the fittest and probably the hardest-working player in the team. Also, because he's not a natural winger he provides an extra body in midfield, as well as being a threat down the right.
