Liverpool must cope without the suspended Javier Mascherano against the Blues after the Argentina international was booked in the second leg of the Real showdown.
Mascherano's absence means that Xabi Alonso is likely to start alongside Lucas in midfield with Gerrard supporting star striker Fernando Torres.
Alvaro Arbeloa and Andrea Dossena will miss the second leg at Stamford Bridge next week if they are booked in the first leg clash."Steven had some problems, but I think he will be OK for Wednesday," said Benitez.
"He was a little bit tired and he felt something a bit tight. We will see."
Gerrard has been the driving force behind Liverpool's recent resurgence and is the joint top-scorer in the Champions League with seven, including two in the thrashing of Real Madrid in the last round.Liverpool skipper Gerrard was a slight doubt for the all-Premier League first leg after being substituted late on against Fulham on Saturday with a slight groin problem
