Arsenal face a daunting task as they bid to reach the Champions League quarter-finals.
After finishing second to Bayern Munich in the group stages, the Gunners were drawn against reigning champions Barcelona.
The teams have met in recent seasons when Pep Guardiola was manager, and over two legs Barcelona were victorious on each occasion.
The one bright spot for Arsenal was their 2-1 win in the first leg in 2011, which saw Andrei Arshavin score a memorable winner at The Emirates.
Arsenal arguably have a better side than they did that night, but Barcelona have a far more dangerous attack.
Lionel Messi, Luis Suarez, and Neymar form the most formidable trio in world football, with ex-Liverpool man Suarez netting an incredible 41 goals this season.
If Arsenal can somehow eliminate Barcelona then they will feel they have a genuine chance of lifting the trophy.
Arsenal will be hoping ex-Barcelona ace Alexis Sanchez can step up, after a few disappointing displays since his return from injury, and this is the big occasion where they really need him to shine.
Here's a look at how the two teams line up...
- Petr Čech
- Héctor Bellerín
- Laurent Koscielny
- Per Mertesacker
