Energie Cottbus have completed the signing of midfielder Christian Muller from Bundesliga rivals Hertha Berlin.

Cottbus said that the 23-year-old player trained with the club while a deal was thrashed out.

An undisclosed fee was agreed for his transfer from Hertha, allowing Muller to accompany his new team-mates as they left for a training camp in Antalya.

"Christian Muller is very talented, and we believe that he can prove that if he gets a regular game," said Cottbus general manager Steffen Heidrich.

Muller becomes Cottbus' fifth signing of the transfer window after the arrivals of Michal Papadopulos, Branko Jelic, Ivan Radeljic and Dusan Vasiljevic.
