Liverpool boss Jurgen Klopp admits he blundered not signing Sadio Mane at Borussia Dortmund.
Mane has played in 76 matches in the Premier League and 19 games in the Champions League.
"I have made a few mistakes in my life and one of my biggest mistakes ever was not taking Sadio when I was at Dortmund," Klopp said.
"We were together in an office and I spoke to him.
"Afterwards I wasn't sure but that was really my fault!
"He's an outstanding boy and life gave me a second chance to work with him and hopefully we can both use it."
