The Blaugrana coach, who is replacing Tito Vilanova for Thursday's Copa del Rey match against Cordoba, has voiced his admiration for the attacker
The prolific attacker beat Cristiano Ronaldo and Andres Iniesta to the prestigious individual award to become the first player in history to win the prize four times in succession, and Roura feels Messi makes everything look so easy.
"We have to appreciate the importance of what he has done, he has made history," Roura said at a press conference.
"t's an enormous achievement, but when you see him every day and see how natural it comes to him and how normal he is, you forget how great he is.
"We have to take our hats off to him."
Messi netted 91 goals in 2012 to break Gerd Muller's longstanding record of 85 goals in a calendar year for club and country.
