The Gunners are on the hunt for revenge. Follow the action here!

Tuesday night's action is headlined by the clash between Chelsea and Barcelona at Stamford Bridge.

From Fernando Torres' last-ditch heroics in 2012, to Barca's controversial victory in 2009, Barcelona vs Chelsea is never short of fireworks.

Then on Wednesday, the big one. The two most in-form teams in world football meet at the Emirates Stadium.

As Arsenal face Bayern Munich, will the Gunners' immovable defence be enough to keep out the free-scoring Harry Kane? And will Arsenal be able to finally overcome their German rivals, after more than a decade of consecutive disappointment at the hands of the Bavarians.

All will be decided in this week's Champions League action.
