Chelsea head to the Emirates Stadium this weekend, aiming to take another step toward the Premier League title.

A win for the Blues would be a nightmare scenario for Gooners, cementing Chelsea's position as the best team in London.

And a group of Chelsea fans have already visited North London to lay down a marker ahead of the game.

YouTubers Chelsea Fans Channel carried out an A-Team-style prank on the Arsenal lettering outside the Emirates, wearing Cesc Fabregas, Jose Mourinho, Didier Drogba and Diego Costa masks.

Take a look at the video above to see what happened.
