Normally when a goalkeeper lets six goals slip by him, he would be quick to criticise his defenders for a lack of protection, or maybe apologise for his own poor performance.
But last night was no normal game for Wojciech Szczesny, who was standing between the Nou Camp goalposts as Leo Messi, Luis Suarez and Co. undertook some shooting practice against his AS Roma side.
Barcelona ran riot against the Italian club, who are usually seen dishing out demolitions of their own in Serie A. And the total football that we have grown used to from Luis Enrique's men was in full flow throughout the evening.

Suarez was able to walk the ball into the net after a flawless team move after 15 minutes and just three minutes later they were cutting through Roma's team again. 27 passes from defence to attack culminated in a tap in for Messi, who delightfully lifted the ball over Szczesny.
The Polish shot-stopper was full of praise for is opponents following the final whistle, describing the sight of six goals floating past him as "beautiful". We're not sure those AS Roma Ultras would agree.
"It was beautiful to watch because we played against a team from another planet," he explained, according to the Evening Standard. "I was in goal playing for Roma but I appreciated what I saw from Barcelona. They were ridiculously good.
"As hard as it is to lose 6-1 it was beautiful to watch."
We always say it at this time of the season, but Barcelona look capable of becoming the first team to retain the Champions League title. They will certainly face greater opponents than AS Roma on their way to doing so with fans already frothing at the prospect of a Bayern Munich v Barcelona final. They appear to be the only club capable of challenging them.
But the Arsenal goalkeeper, on loan in Serie A for the season, was right when he said he was watching a team from another planet. Take a look at some of the best footage of the match below!
