With Saprissa he won two national championships, as well as an UNCAF Cup title and a CONCACAF Champions Cup title. After the Clausura 2007 tournament, he signed with Italian businessman Matteo Quintavalle, which meant his departure from the team, seeing as Quintavalle is not a FIFA-licensed player's agent, and Saprissa would not negotiate with him. Quintavalle was accused of fraud, and Alemán left Quintavalle (after a breach of contract by Quintavalle), and signed with Puntarenas F.C. on his own. 5 days before the transfer window closed, Aleman signed with Liberia Mia, but was allowed to play 2 more matches with Puntarenas against Saprissa, one of them for the UNCAF Cup Semifinals. Later he signed with Brujas but in January 2010, he returned to Saprissa. Alemán participated in the 2005 FIFA Club World Championship Toyota Cup with his team, who ended up in third place, behind São Paulo Futebol Clube and Liverpool F.C..
