With Arsenal sitting seventh in the Premier League, the Gunners are playing in a more defensive fashion, with Arsene Wenger preferring to use his wingers in a 3-5-2 formation.

However, there are times when they prefer a 4-4-2 diamond, and this tactic has paid off.

The result is a side that has scored five goals in their last six matches, including two against Chelsea, and are unbeaten in their past five league games. 

The key to Arsenal’s recent form is that they have been able to find success against the bigger sides.

Against West Ham last week, they were able to secure a draw thanks to two late goals from Gabriel Paulista and Alex Iwobi. 

Against Newcastle on Saturday, they won 4-2 thanks to a brilliant strike from the Argentine and a late winner from Aaron Ramsey.

Arsenal have also been able and comfortable playing the ball around the pitch, as they were at the heart of the 3-1 win over Chelsea last weekend.

They have scored five of their past six goals inside the opposition half, including a brace against the Blues, while they also had a second in the first half from Alexis Sanchez, who added a third in the second half.

This type of attacking style has been effective in the past, with Chelsea having won just once against Arsenal in the league since January 2011.

It was against the Hammers that Arsenal were awarded a penalty, which they duly converted.
