Liverpool manager Jurgen Klopp admitted match-winner Roberto Firmino had no chance of playing against Paris St Germain until he arrived at training on Tuesday morning and declared himself fit.

The Brazil international was set to miss the Champions League opener because of an abrasion on the cornea of his left eye sustained in Saturday’s win over Tottenham.

He did not train with the squad on Monday, but, having said he was ready to play, came off the bench to score the added-time winner in the thrilling 3-2 victory over PSG at Anfield.

“There was no chance yesterday, absolutely no chance the day before, and this morning he came in and said, ‘I’m fine, I can open the eye again’. That helps. It was good,” said Klopp, who had seen his side squander a 2-0 lead given to them by Daniel Sturridge – Firmino’s replacement – and James Milner’s penalty.

“Yesterday it didn’t look really well, we had only one session, which we really used, this morning and Bobby tested a little bit but then he went in.

“And I really think it is a moment where you have to show faith in the squad. Yes, when you have Bobby Firmino available, you actually always think, ‘Come on, bring him’.

“But it was nice to see how Daniel performed tonight and he paid 100 per cent back so that’s so cool for him, for us, such an important sign.

“Then bringing Bobby after 70 minutes, it’s a nice tool to be honest, I really like that. So it was good.”

After the game, a brief moment was captured on video as Firmino was giving post-match interviews in the tunnel.

Whilst speaking to the press, the Brazilian striker was interrupted by his international teammate and PSG star Neymar.

The two embraced and the PSG man had just a few words for his countryman.

"Congratulations, you played great."
