Arsenal have to be favourites to win the Premier League now. It is very clear they are going to take some shifting from the top of the table.
The only thing we don't know about Mikel Arteta's side yet is how they will cope with being frontrunners in the second half of the season. But it doesn't look like their inexperience of being in a title race is fazing them at the moment.
In the first half we saw their attacking intent and creativity, pressing Spurs to keep them penned in their own half and then capitalising on their mistakes.
