Talk before the clash was of Spurs closing the gap on their neighbours but the possibility of their first league win against Wenger's men was effectively over when Robin van Persie and Cesc Fabregas struck just before the break within a minute of each other.
Van Persie added the third in the second half, with Wenger's men unbeaten in 11 games in all competitions and establishing their title challenge.
"Do we have enough? I say yes," the Frenchman said. "I've said that since the first day of the season and it won't change now.
"We want to show consistency and intelligence and that is not easy. I believe we have the opportunity and it will be down to our attitude."
Robbie Keane suggested earlier in the week that Spurs' squad had a greater strength in depth, although the defeat puts a question mark over whether they will compete with the traditional heavyweights.
"We have to see over a longer period," Wenger said. "I am positive for us because we have the minimum points with the performances we have produced. Will Tottenham be up there? I don't know. It's too early.
"It is not about opinion, it is about performance on the pitch. That is what is important."
