Berlin, May 6 (IANS): German football side FC Cologne's striker Anthony Ujah will join league rivals SV Werder Bremen at the end of the season.

The Nigerian international passed the medical test a few days ago before penning a four-year deal on Tuesday to reinforce the "Green-Whites" offence next season, reports Xinhua.

Newly-promoted Cologne will thus lose their top scorer, who marked ten goals this season so far.

"We intensively observed him for a long time to get a comprehensive picture. He is fast and prolific striker who still can evolve with us," Bremen's sporting director Thomas Eichin said.

Bremen's new arrival joined Cologne in 2012. The 24-year-old provided ten assists and 34 goals in overall 104 appearances.

Ujah's current side Cologne sit currently on the 11th place in the standings meanwhile Bremen still battle for an Europa League berth.

The 24-year-old striker made his first international debut for Nigeria against Mexico in June 2013. He has so far played five matches for the "Super Eagles".
