Gerrard is delighted Hamann is now sure to make the final appearance which will extend his deal by 12 months.
"I would like to keep him for as long as possible," he added.
"It's not just having him in the squad as a player, but he is a great person to have around as well. It's quite a young midfield and every one of us can learn from Didi."
Rafa Benitez will check on the fitness of Xabi Alonso before deciding if Hamann retains his place against the Portuguese in the Stadium of Light.
The Reds headed to Portugal today with Robbie Fowler back in the fold after being forced to sit out the weekend's cup success.
