Mathieu Flamini made a disastrous contribution towards Arsenal's Champions League hopes as he gave away a crucial penalty in their clash with Barcelona.
The Frenchman came off the bench with 10 minutes to go and conceded a penalty within 50 seconds, with his first contribution.
Lionel Messi gladly converted, to score his second goal of the night and give Barcelona a 2-0 lead, with two important away goals.
Former midfielder Emmanuel Frimpong reacted angrily to Flamini's error, posting this on Twitter:
What a contribution there Flamini bloody hell— EMMANUEL FRIMPONG (@IAMFRIMPONG26) February 23, 2016
Arsenal now face an uphill battle to progress to the quarter-finals, and their match in the Nou Camp will feel like a trip into the lion's den.
Former Gunners goalkeeper David Seaman also commented on Twitter after the defeat, and said that Arsenal were simply beaten by the better team on the night.
Sometimes you have to put your hands up and say "they are a great team!! #barcaquality— David Seaman (@thedavidseaman) February 23, 2016
Even so, having got to 71 minutes at 0-0, it felt like a draw was there for the taking for the Gunners, only for a superb counter attack a penalty to undo all their hard work and set up a very long 90 minutes at the Nou Camp.
