Pep Guardiola announced at a press conference on Friday that he was stepping down as Barcelona manager at the end of the season. With the 41-year-old deciding not to renew his contract, Barcelona president Sandro Rosell also broke the news that Guardiola's assistant, Tito Vilanova, will take the helm from next season.

''The reason is simple, four years are long and they wear you down,'' Guardiola said, according to the Associated Press. ''I think that sincerely that the next person will have things to bring that I can't.

''Every day during four years, the demands are very high, the pressure, the necessary energy to push the players and enjoy it. I need to rest and move away.''

Guardiola leaves as the most successful coach in the illustrious history of the Catalan giants. The 13 trophies amassed since Guardiola took charge in 2008 including two European Cups and three La Liga titles.

In bringing the best out of products of the club's famed academy, like Lionel Messi, Xavi Hernandez and Andres iniesta, Guardiola's time at the Camp Nou will be remembered not only for the amazing success but by the stylish and hard-working manner in which it was achieved.
