Michael Barrantes Rojas (Spanish pronunciation: [baˈrantes]; born 4 October 1983) is a Costa Rican professional footballer who currently plays as a midfielder for Puntarenas.

[5] The following season he secured for his team the 2008 league title when he scored the winning goal in the last playoff match against LD Alajuelense.

[8] In July 2010, after delivering an impressive display during Saprissa's European tour,[9] he was signed by Norwegian side Aalesunds FK on loan, joining his compatriot Pablo Herrera who was already at the club.

[13] He received his starting debut with Aalesunds on 12 September in an away loss against Odd Grenland, during which he caused a penalty 50 seconds into the match.

[15] The following season proved to be much more successful for Barrantes, as his game play not only saw him become the center piece of the Aalesunds midfield, the club also decided to make the loan-spell permanent, six months ahead of time.

[23] In addition he crowned the season with winning the domestic cup when Aalesunds beat SK Brann 2–1 in the finals, with Barrantes scoring twice and securing the title.

[38] Barrantes made his debut for Costa Rica in a February 2007 friendly match against Trinidad and Tobago and went on to earn 54 caps, scoring four goals.
