Having conceded a goal after 18 minutes and another just after an hour, adding to a 2-0 deficit from the first leg earlier this month, Arsenal are facing a real mountain to climb at the Nou Camp.

From 200 fixtures in the Champions League, Arsene Wenger has never claimed a win at Barcelona's home ground - and to make matters worse, the Catalans are miles above their domestic and European competition at the moment with Lionel Messi, Luis Suarez and Neymar - otherwise known as MSN - scoring an incredible 105 times already this season.

But as the Gunners attempt the seemingly impossible, January signing Mohamed Elneny has delivered a vital lifeline for the Premier League outfit.

Indeed, some smart play in the final third combined with expert movement from Arsenal's midfield created a pocket of space for the Egyptian international just outside the penalty box, allowing him to apply a curled yet powerful finish into the top corner that Barcelona's four-time Ballon d'Or winner would be proud of.

Needless to say, Arsenal fans have been expressing their jubilation on social media - although their side need to score three more times to go through!
