Almeida pledges future to Werder
The 26-year-old, who has won 33 caps for Portugal and scored 12 goals, is under contract at Werder until June 2011 and is valued at around €7million.
Spanish giants Real Madrid, Sporting Lisbon and Valencia are all reported to be interested in signing him.
He has scored nine league goals this season, even though Werder have struggled for form and exited the UEFA Champions League last night despite their 3-0 home win over holders Inter Milan.
"I am staying," he told the newspaper Weser Kurier with his side tenth in the Bundesliga.
There is a risk Almeida could leave the club for nothing on a free transfer next June, but the crowd-favourite has said that is not an option.
Werder face league leaders Dortmund on Saturday.
