Cristiano Ronaldo was responsible for Bayern Munich's exit from the European stage last month and Thomas Muller has elevated the Real Madrid attacker, as well as Lionel Messi, above all others.
Consistently outdoing eachother in their quest for glory, the LaLiga pair have often sparked debate over who betters the other, although Muller places them on a level footing.
"Basically we all know that [Ronaldo] is extraordinary, in his appearance and with his sporting performances - he's already a phenomenon," Muller told reporters. "You cannot achieve such a number of goals for so many years and so often without having to work hard.
"He has enormous physical and technical qualities, of course. But what impresses me the most are his heading skills. This is sometimes forgotten a bit. He has fine technique, but he also has great heading skills.
"And if you look at him and Lionel Messi, the two are on a level above all others."
