Barcelona's historic comeback against Paris Saint-Germain in the Champions League is now but a distant memory - yet it still feels hard to believe.No one - and I mean no one - expected Luis Enrique's men to overturn the 4-0 deficit from the first leg but, incredibly, they did just that.Three goals in the last seven minutes saw Barcelona win 6-1 at the Camp Nou (6-5 on aggregate) and progress into the quarter-finals of the competition.Even PSG's players looked in utter shock, though the defeat will have inevitably hit one player harder than most.Adrien Rabiot was the target of some serious trolling - mainly by Neymar - after the game having gloated about their 4-0 win over Barcelona on Instagram.In a picture with Layvin Kurzawa, the Frenchman held up four fingers to signify a result he probably thought would fire PSG through to the next stage.But it didn't, so when Barcelona won 6-1 to progress, Neymar mercilessly hit back by editing Rabiot's picture to read "4+2=6", alongside some crying laughing emojis.Not Rabiot's smartest move, I think you'll agree.The 20-year-old has since had time to reflect on what happened in Catalonia and, speaking to L'Equipe on Sunday, he admitted to having one major regret about the game.But it had nothing to do with his social media activity. According to Rabiot, he was actually ill before the game and wasn't well enough to play against Barcelona - but he did anyway.

"I played with a chest infection," he said after Sunday's 2-1 win over Lyon, per Goal. "I wanted to play this game and it was not the best thing.

"Now I'm good, but I regret it because I was not 100 per cent.

"Maybe we should have put someone else in my place. It's clear I was in trouble, even if the outcome was not all because of that."

Rabiot's admission goes some way to explaining his poor performance at the Camp Nou because, in all honesty, he wasn't at the races at all.

In stark contrast to the first leg, where he memorably dominated Lionel Messi in the middle of the park, Rabiot struggled to contain Barcelona's midfield.

Had the youngster given way for a fitter Grzegorz Krychowiak, perhaps PSG would have held on and been the team to make the quarter-finals.

Not that Rabiot was solely to blame for PSG's defeat, because each and every one of his teammates was equally poor. At 4-0 up, Les Parisiens were out of sight and should have comfortably won the tie.
