Argentina's new coach Edgardo Bauza arrives in Barcelona on Tuesday on a mission to convince Lionel Messi to reverse his early international retirement and come back to the national team. Bauza, who started the job on August 1, left Buenos Aires on Monday night on a Barcelona-bound flight. The 58-year-old coach says his number one job is convincing the five-time World Player of the Year to return to a national team where he has endured a string of disappointing losses in big tournaments.
