Arsenal are a side that will give the Blaugrana few surprises, having been dispatched by the Catalan giants in the knockout rounds of 2010 and 2011.
Cesc Fabregas and Alex Song would also be facing their old club should Barcelona be paired again against the Londoners, with the former expressing his delight at the possibility.
Arsenal's form has been anything but convincing of late, dropping points in the league with worrying consistency and failing to impress anyone of their quality even when they win all three.
Jack Wilshere was one of Arsenal's best players two years ago at the Camp Nou, and he recently returned to full match fitness after a year-long injury absence.
Santi Cazorla, the Spanish playmaker and summer transfer, has been Arsenal's main attacking threat this season, with Olivier Giroud, Lukas Podolski and Theo Walcott all struggling to find consistency in their form.
Alex Oxlade-Chamberlain has recently been given a run in the side, and he could be a dangerous wild card down the right, running at an exuberant—but never eager to defend—Jordi Alba, should he get the chance.
Arsenal have long been compared to Barcelona in their style and outlook on the game, but without a major trophy since 2005, they've been unable to produce the same success to match their style.
The two recent ties required impressive performances by Barcelona in the return legs at the Camp Nou, with Arsenal leading for a time in each. This year's Arsenal team, though, may be their weakest in a decade and a half and shouldn't give the Blaugrana too much to worry about.
