The Gunners will be looking to maintain their new found form when they travel to face Everton on Tuesday in the Premier League.
Arsene Wenger has revealed his team news ahead of the game and said that he will be without Mustafi and Ramsey.
Mustafi picked up a hamstring injury in the game against Stoke City last Saturday after playing for just 25mins.
Speaking in his press conference on Monday, as confirmed by ESPN FC correspondent Mattias Karen in the tweet below, Wenger revealed that Mustafi has an estimated three-week recovery period.
Wenger says Aaron Ramsey "still not ready" for Everton game. Estimate for Mustafi is still 3 weeks out.

That will rule him out of games against Everton, Manchester City, West Bromwich Albion, Crystal Palace and Bournemouth over a busy Christmas period.
