Former Liverpool defender Jamie Carragher ranks Mario Balotelli as the club's worst signing during his time at Anfield.
Balotelli, 25, signed for Liverpool from AC Milan in 2014 for a fee of £16 million.
But the Italy international managed just one Premier League goal for the Reds before being loaned back to Milan last summer.
And Carragher, who retired from football in 2013 after making 508 Premier League appearances for the Reds, was shocked the club opted to bring in Balotelli.
The ex-defender was also left disappointed with El Hadji Diouf and Alberto Aquilani's performances at Anfield, who joined from Lens in 2002 and Roma in 2009 respectively.
When asked who he rates as Liverpool's worst signing during his time at the club, Carragher said in the Daily Mail: "There's been a few.
"El Hadji Diouf has got to be up there. Alberto Aquilani would have to be up there as well. We spent a lot of money on him. He was signed injured, he left injured and I can't remember him not being injured.
"I can't believe we signed Mario Balotelli! The thing with Balotelli is everyone always says it's the off-the-field antics, but I wouldn't care if he was doing it on the pitch.
"People tell me he's got talent but I can't remember him having a good game. I'm praying with all the money in the Chinese Super League that someone is going to buy him after his loan. I don't think anyone in the Premier League will take him. He has to be No. 1 with Aquilani and Diouf."
