El-Hadji Diouf admits he wants Roy Keane to pledge his future to Sunderland.
The manager is locked in talks with the Wearside club's hierarchy about extending his current deal at The Stadium of Light.
Keane has insisted he will not be rushed or pressurised into penning a deal, but Diouf is hopeful and confident the Irishman will soon sign on.
"Of course, I hope Roy Keane stays here more than four years because I have a four-year contract," Diouf told Sky Sports News.
"That is why I came here because of him, he is a great manager and I want to see him on my back during training - I know this is the team for him too."
Diouf admitted Keane was a big influence on his decision to move to Sunderland in the summer.
"The thing that impressed me, was that there is nobody else like him - I played against him for Manchester United against Liverpool," he said.
"But he is a nice guy, nice manager because he knows football - he has played at the highest level and he knows football, everything he asks on the pitch he knows about."
