a group of chelsea fans stormed arsenal 's emirates stadium this week in a lighthearted attempt to lay a blue marker down as the premier league clubs prepare to do battle on sunday .
the four fans labelled themselves the ` c-team ' while wearing jose mourinho , didier drogba and cesc fabregas masks to hide their identity before parking up outside arsenal 's north london home .
the group of chelsea fans set off blue smoke bombs and covered the arsenal sign outside the emirates .
the blues know victory against arsenal on sunday will all-but secure the premier league title with mourinho 's side needing two wins from their next two games .
