Good evening and welcome to LIVE text commentary of the first leg of the Champions League last-16 clash between Arsenal and Barcelona at Emirates Stadium. It's a daunting task for Arsene Wenger's men who will surely need to conjure up one of their best performances of the season to give themselves a chance of ending the Catalan side's 32-match unbeaten record. Keeping the MSN strike-force at bay will be top of Petr Cech's wish-list as the Gunners look to snare an advantage to take to the Camp Nou for the second leg on March 16. Arsenal lost to Barca over two legs in 2010 and 2011 - can they make it third time lucky in 2016? It's a mouthwatering prospect and all gets underway at 19.45 GMT.
