Rangers frustrated the 2006 champions with a solid performance in the 0-0 draw at Ibrox two weeks ago, and this time the winner could book a place in the last 16.

"Like Frank Rijkaard (Barca manager) says, you should never underestimate any rival and must respect them - Rangers deserve our respect.
"They were determined not to lose in Glasgow and fought for it in their special way."

"You have to give them credit, though of course we want to beat them tomorrow."
