It's amazing how much of a difference a week can make in football.
Before the match against Nottingham Forest last week, Arsenal were looking for their first win in five Premier League matches.
Seven days and the talk is all about how Mikel Arteta's side look back to their best and have the chance to build momentum in the title race.
They comfortably beat Forest before demolishing Sporting 5-1 away from home in the Champions League.
Arsenal enter the busy December period in good spirits and, depending on their progress in the Carabao Cup, are not scheduled to travel outside of the south of England for a match until late January, which can only help their preparation.
