Rangers boss Giovanni van Bronckhorst has branded Jurgen Klopp's Liverpool as "long ball".
Gers host Liverpool tonight in the Champions League.
"It's always important to keep focus but it will hectic because Liverpool's playing style is direct with long balls, runners and they have a lot of pace," Van Bronckhorst said.
"Mentally, we have to be strong and make sure we stay with 11 men."
Van Bronckhorst also admitted Rangers need to beat Liverpool to keep their hopes alive.
"Ideally we need 3 points against Liverpool," he added. "We have to see other results but we want to proceed in Europe when we play our last game at home against Ajax.
"Liverpool is a team who has been in three finals in five seasons, they have a top coach, top squad with balance. Even with injuries they can still field a strong side. It's the first time we play against them [at Ibrox], but it would be a great win if we achieve it."
