Karius: Too early to compare Salah and Ronaldo

Salah and Ronaldo will be taking up all the headlines in the build up to the Champions League final, as both players will lead their teams from the front. 

"This season is unbelievable. He's of course in that region but the biggest difference is Ronaldo did this over so many years. It's too early to put Mo with him", Karius told 'Sky Germany'.

"I don't want to take anything away from Mo - he's world class this season. But Ronaldo showed over so many years to be up there with the best, you have to prove it season over season.

"I hope he can do it. I wish he can do it. He's still really young and has a lot of space to improve even more."
