London derby should not be close

Today is the replay of my last week perdiction. This game is @ Arsenal and they're -120 to win. Tottenham are under acheivers and will get displaced today. Last week Arsenal had their second squad on the pitch and still came away with a draw on the road. Wagering $600 on the Gunners to win. Playing a $100 parlay with game going over 2.5 goals +105.
