The five-time Ballon d'Or winner added another couple of goals to his growing collection on Sunday evening in Barca's 5-0 rout of Real Betis at the Villamarin.
Valverde insists that Messi has earned the right to be described as the best talent to have ever kicked a ball, and does not expect anyone to rival his status as the greatest of all time once he eventually calls it a day.
Speaking to reporters after the Betis win, the former Athletic Bilbao chief said: "You have to enjoy him. We have been able to live his era. I have suffered because of him and I know what that is like.
"Now I can enjoy it. It is an event to watch him every day. He is the best player there is and there ever will be."
