The former Slavia Prague defender said that he is close to sealing a move to the German club and hailed the Bundesliga as one of the top competitions in Europe
The 25-year-old, currently on the books of Slovan Liberec, has started both Euro 2012 matches for Michal Bilek's men, who sit second in Group A with three points from two games.
Selassie claims that a number of European clubs have been tracking him for a while, but says that a move to Werder Bremen is looking like a strong possibility.
"There were some offers in January, CSKA Moscow's interest was known by everyone, but I would say that there are more serious offers now," Selassie wrote in his blog for Czech newspaper Sport.
"I am close to joining Werder Bremen, but I am only focused on the Euros now.
"The Bundesliga seems to be a good competition. I watch it sometimes, especially now, with players like Petr Jiracek there.
"This is one of the best leagues in Europe, it would be great to play there."
Selassie then highlighted the importance of Saturday's match against the Euro 2012 co-hosts.
"We are now waiting for the game against Poland, which will be the biggest match of my career," he added.
