Lionel Messi leaving Barcelona and starting a fresh challenge elsewhere would make things interesting for football, according to Bayern Munich attacker Thomas Muller.
Six-time Ballon d'Or winner Messi informed Barca on Tuesday he wants to leave after 19 years at the club and it is believed he wants to activate a possible clause to leave on a free transfer during the current window.
Inter, Paris Saint-Germain and Manchester City, who are managed by former Barca boss Pep Guardiola, are considered the realistic candidates to sign the 33-year-old.
Muller considers Messi to be arguably the greatest footballer of all time and is intrigued to see where the superstar forward ends up if granted his wish to leave Camp Nou.
"The day Messi and Barcelona go their separate ways had to come at some point," Muller said at a promotional event for Hoffner.
"Of course, you would have thought that would be the end of his career but now it seems to be different.
"Lionel Messi is one of the best footballers on the planet, maybe even the best of the last 100 years, although everyone will have their own opinion.
"If you ask Mr. Pele, he may see things slightly differently! But now there will be a change and it could become interesting for football.
"Besides Barcelona fans, which I understand, nobody views this in a bad way, but are instead curious about what new paths could open up."
