The Gunners went behind to Harry Kane's goal in the first half but rallied in the later stages of the game and managed to grab a draw thanks to the Kieran Gibbs' goal.
"From Arsenal's point of view, it's as bad as I've seen them, in terms of being disjointed, in such a big game," Neville said on Sky Sports.
"They finished really strongly, but the first half was the first time I've seen the midfield two look like I thought they might be in the Premier League, which is overrun and lacking in power.
"It was so difficult for Cazorla in particular, who was hauled off at half-time, they say he was feeling unwell. Well, I have a feeling there was case for taking him off even if he wasn't unwell, because Tottenham were brilliant. They got back into the game, though, and I think both managers can be happy for different reasons."
