Jurgen Klopp has admitted that he wanted to punch himself after turning down the chance to sign a Liverpool star whilst he was in charge of Borussia Dortmund.
Klopp's Liverpool head into the weekend as the Premier League leaders, having scored more goals (30) than anyone else, and face a potentially tough trip to St Mary's to face Southampton.
The German manager was considering bringing in one of his current players back in 2014 but wasn't convinced about him as a player - however he quickly realised that he had made an error.

Ahead of Saturday's game, Klopp explained that he mulled over signing Sadio Mane from Austrian side Red Bull Salzburg before the Senegalese forward moved to England, and also claimed that he didn't hesitate to bring him to Merseyside when the opportunity presented itself.
Klopp on Mane
The 49-year-old told reporters, via Goal: "With Sadio it was pretty simple because I made the mistake at Dortmund where I didn't take him. We talked. I think everyone knows we met each other and by the end I didn't feel this (claps hands together).
"Around about three months later I would have punched myself, so I knew already that the next chance I had I would take it. So it was not difficult to take this decision, it was very easy.
"When the club came and when Michael Edwards (Liverpool's new sporting director) said we have an opportunity, no talks were necessary anymore. It was a case of 'let's do it'."
Mane's huge £34 million transfer fee made him the most expensive African footballer of all time, but he hasn't let that affect his performances, starring for the Reds and currently the side's top scorer in the league with six goals.
Why didn't Klopp sign Mane at Dortmund?
Klopp continued: "I don't know why I didn't sign him before. I like the player, it was more of a feeling. At Dortmund we could only get one player for this position, not two or three, so it needed to be exactly the right fit in this moment.
"I've said a lot of times, I'm not a genius and I couldn't exactly imagine where he was in terms of playing in the Austrian league, and what does the Austrian league mean for the football (at Dortmund)?"
"I have made more mistakes in my life like this but he would have been more expensive if we had taken him to Dortmund and then he had been sold to Liverpool, so all good for Liverpool. The more I think about it, that was my first Liverpool decision. Nice."
Liverpool are unbeaten in 12 games across all competitions and Mane will be looking to impress later today when he returns to his former club, as his current team look to extend their lead at the top of the table.
