The Spaniard has revealed Jurgen Klopp's side were unwilling to match his €4 million release clause at the time but says he is excited at the prospect of life in the BundesligaAlejandro Galvez said he was in discussions with Borussia Dortmund before opting to join Bundesliga rivals Werder Bremen.
After two years at Rayo Vallecano, free agent Galvez signed a three-year deal with Werder at the end of the 2013-14 season.
Galvez was reportedly attracting interesting from several European clubs, including Manchester United, and has now confirmed he came close to a deal with Dortmund until they opted against matching his release clause.
"We met in a hotel and talked about a change," the 25-year-old, who made 26 La Liga appearances last season and scored two goals, told Bild.
"I had an exit clause of €4million but Dortmund did not want to pay for it. Then they decided to [go for Greece international] Sokratis Papastathopoulos."
Galvez added: "It would have been a good option, but I knew that a new one would come along. Werder is a new option."
