Liverpool defender Billy Koumetio has revealed how big an impact Sadio Mane would have around the club.

Mane left last year for Bayern Munich and is now playing for Al-Nassr

Koumetio, currently on-loan with Dunkerque, told the Liverpool Echo: "Sadio is always the one who was there before everybody. He works really hard. I came also early one time, but not as early as Sadio, so I was seeing him working in the gym. I was like, 'Wow! He is working in the gym already.'

"This is the time when people come in and go to eat, but he's not eating. He's there, working in the gym. 'Wow'. He was doing sit-ups, and sit-ups, and sit-ups. 'Wow'.

"I went to get changed and went to get something quickly to eat. Came back to the changing room, and then went to join him in the gym. I saw him working, and then the squad came 30-45 minutes afterwards, and he was still working there! He was the last to go out of there. 'Wow.'"
