Liverpool defender Martin Skrtel rates Real Madrid star Cristiano Ronaldo the best in the world.
Real are at Champions League opponents Liverpool tomorrow night.
"For me, Ronaldo is the best in the world, but everyone knows the Real players - in my mind they are the best team in the world, so yeah, it is a challenge for us as a team now," said Skrtel.
"You play Real Madrid in the Champions League, of course it's a real challenge.
"This is what we play for. The Champions League is the best competition in the world, because you face the best players in the world. It's a great game, and we will do our best to show we're able to compete with the best, and I believe we can get a result against them."
