It was the presence of Benitez that persuaded Sissko to choose Liverpool ahead of Everton. "I have a great deal of respect for Mr Benitez. He helped me a lot at Valencia and he was the main reason why I decided to come to Liverpool," said Sissoko.
"He showed last season with Liverpool what a great manager he is and I want to be a part of this club's future. I know all about the history and tradition of the club and I am honoured to be here.
"As well as the manager I already know some members of the backroom staff and some of the players. That will help me settle in.
"I'm just looking forward to challenging for a first team place now. There are a lot of great midfielders here already and so I know it's going to be difficult, but I am still young and highly motivated to prove my worth."
The comparisons with Viera will not faze Sissoko who says he is flattered by them. He said: "It's always nice to be compared with great players but it's not a problem for me. It doesn't put me under any extra pressure at all.
"I am still young and have a lot of work to do before I can be compared to Vieira. It's a good target for me to aim for."
