They may be just two points off the top spot in the league, but it's safe to say the Gunners haven't been firing on all cylinders this season.
A goalless draw with Hull City on Saturday means Arsenal have added another game to their already congested fixture list - although it still
doesn't compare to what their opponents on Tuesday night have had to put up with.
Barcelona, on the other hand, just can't seem to stop scoring this season. Their front line of Lionel Messi, Luis Suarez and Neymar might be the best ever assembled, and it's showing in the goal-scoring charts this year.
