Compared to last season, Tottenham have scored 9 more goals at this point of the year (64).
Spurs are the 21/20 (2.05) favourites for Saturday's clash at the time of writing, having settled into Wembley well and won four of their last five Premier League clashes at this venue. To do that they'll have to fix their very bad away form.
The same goes for Harry Winks and Danny Rose, both of whom will start on the bench on Saturday. They need to win away from home against Spurs for the first time since March 2014 to inject a bit of hope into their league season.
Wembley is Tottenham's temporary home for one season only, making a league north London derby in an "HA" postcode rather than an "N" one a very unique event. Arsenal will also continue to be without Santi Cazorla. It is so usual to see Arsenal win a game, enthrall every single fan in the world because of it and get embarrassed in the very next game. That loss came earlier this season.
Arsenal are now in sixth place in the Premier League table as they bid to try and break back into the top four this season.
The meeting between Tottenham Hotspur and Arsenal will be the first in the Premier League era at Wembley.
Spurs have dropped 37 points from leading positions in Premier League games against Arsenal - more than any team has against another in the competition's history. But as it is, the 24-year-old is banging in goals for fun across North London and has established himself as one of, if not the best centre-forward in Europe, in the process. It would put them seven points ahead of Arsenal and, if not eliminate their rivals from the squabble for the three places behind Manchester City, render them rank outsiders.
Wenger came to the defence of his new striker at yesterday's press conference, explaining that maybe after the Bundesliga's winter break "he was not ready physically to perform at his best, but I don't believe that he didn't want to perform".
Danny Welbeck will be out of favour, with club record signing Pierre-Emerick Aubameyang impressing on his debut.
On the other hand, Arsenal have had an indecent spell. They surged into a four-goal lead in 37 minutes against Everton.
