Arsenal have been preparing themselves for a huge clash on Tuesday night as they host Chelsea at the Emirates Stadium. The Gunners have gone four games without a win in the Premier League and will be hopeful that their struggling local rivals can help provide that spark once again.
A win could see the north London outfit move back to the top of the division, though that may only be temporary as Manchester City hold games in hand. While the title race is out of their control, Mikel Arteta and his players will have to do everything possible to ensure that any slip-up from their rivals can be capitalised upon.
Heading into the clash with the Blues, plenty of training photos have been released, including some interesting hints at how the side have prepared for the tie. With that said, here's a look at a few things spotted ahead of the big London derby on Tuesday night.
