The 20-year-old Club America defender announced the move on his Twitter account Monday, saying that he would join up with the Portuguese outfit in six months.
"An important dream of mine is coming true, but I'm focused first on the Clausura 2013 with América, with whom I have another dream [to win the league championship]," Reyes posted on his account.
Reyes debuted with America in 2010 and quickly became a star. The defender also played a big part in Mexico's gold-medal run at the Olympics in London, and has been part of El Tri's senior setup since 2011.
The move is rumored to be for around 7 million euros, though the exact figures of the deal are not known.
“I’m out to write my own story,” Reyes said. “I don’t have to imitate anyone, and I’ll write my story the way I want to.”
Mexicans Francisco Fonseca, Manuel Negrete, and most recently Reyes’ U-20 teammate Edson Rivera have passed through Portugal without the desired results, but Reyes is taking a different perspective on what he hopes is the next step in a budding career that has him ranked among the world’s most promising young central defenders.
In the meantime, he’ll play one more tournament with Club America, the team where Reyes debuted as a 17-year-old.
Club America Sporting Director Ricardo Pelaez said that the transfer would go down as the biggest in the long history of the club, but that the main idea was to allow Reyes to continue to grow as a player instead of holding him hostage in Mexico.
“We didn’t want to cut his wings, as we’ve said,” Pelaez told Televisa Deportes. “We wanted to give him this chance to grow as a player, but for us it was very important to keep him even if it was for another six months.”
