Former Tottenham boss Terry Venables feels they've now overtaken Arsenal as North London's top dogs.
The two clubs meet this Sunday.
Venables told The Sun: 'Tottenham appear to be getting stronger while Arsenal seem to be weakening.
"Spurs are strong in defence and midfield and have pace going forward. Arsenal, unusually for them, look vulnerable in defence.
"They are also inconsistent. They get on a run of four or five games when you think they have put all their problems behind them, and then they revert to type.
"There is no doubting their footballing ability - there are few teams better to watch when they are firing. But these days they don't fire regularly enough.
"But you do not get a medal for being the best team in North London. Both teams should be aiming higher than that."
