Gerrard's cousin Anthony Gerrard is expected to be at the heart of Cardiff's defence.
Steven told liverpoolfc.tv: "It would be great to have another Gerrard in the Premier League.
"He is a good player and I think he has got the potential to hold his own. I know that is what he is desperate for.
"He has been injured. He missed the last two games because of a calf problem but speaking to him on the phone there is a chance he could be ready for the final.
"We have a good relationship and I will be sending him good luck messages beforehand.
"I would love nothing better than for him to get to the Premier League."
