Jamie Carragher has given Mamadou Sakho the thumbs up after revealing he has played alongside Liverpool's new £17million defender.
Carragher says he partnered Sakho at centre-half in a charity match in Corsica last year organised by Gerard Houllier.
The Anfield legend was impressed by Sakho and remembers how Houllier tipped him for greatness.
"I played alongside Sakho," Carra told the Liverpool Echo. "How did it go? Well we won 2-1! I talked him through it and he was fine.
"I remember on the flight home, Gerard Houllier having a really good word with him, even though he wasn't his manager, saying what he needed to do to improve.
"I thought that was typical Gerard, always attention to detail.
"He wasn't even his player, yet he was trying to improve him. He later said to me, 'he's going to be a player, him'."
Brendan Rodgers was delighted to land French international Sakho and Carragher is impressed by the options Liverpool have at the back.
"He's at a great age," he said. "Physically he's ready for the Premier League, it will just be interesting to see where the manager brings him in.
"He's left-sided and there's competition for places everywhere now. Cissokho's been brought in to put pressure on Enrique, Skrtel's done really well in the Manchester United game, while Toure's been a revelation. In the first three games he was superb so he'll be looking to get him back against Swansea.
"Competition is what you want, but of course you don't want your best players on the bench.
"I think the manager just has to juggle it round a little bit now and use the best two. The young lad Thiago Ilori will be one for the future I think, maybe next season, but the sort of money that has been spent on Sakho would suggest he is going to be a starter."
