Berlin: Germany winger Marco Reus has ended speculation over his future by signing a four-year extension to stay at struggling Borussia Dortmund, the Bundesliga club announced on Tuesday.

With Borussia battling relegation after a series of poor league results, there had been speculation Reus was set to leave at the end of the season.

The 25-year-old had been linked to Dortmund’s rivals Bayern Munich, as well as Real Madrid and Manchester United, due to a clause in his old contract, which would have allowed him to leave in June for 25 million euros (Dh103.98 million).

But Reus has silenced the speculation by putting pen to paper on a new deal with the eight-time German champions, which contains no release clause.

“I am very happy with my decision for Borussia Dortmund,” said Reus. “Dortmund is my home town and Borussia is simply my club.

“I look forward to a successful future with our team and our fantastic fans behind us. There is plenty to do and I want to really get stuck in.”

Reus’ new deal is a huge relief for Dortmund’s bosses, having seen star midfielder Mario Goetze leave for Bayern Munich in 2013 to be followed by striker Robert Lewandowski last year.

Borussia face Italian league leaders Juventus away in the Champions League last 16, first-leg, on February 24 with the home leg on March 18, but are currently 16th in the German league.
