Borussia Dortmund secure Oliver Kirch signing

Borussia Dortmund have reportedly completed the signing of midfielder Oliver Kirch from Kaiserslautern.

According to SportBild, the Bundesliga champions have paid around 500,000 euros for the defender.

It is believed that Kirch will provide cover for first-choice right-back Lukasz Pisczcek, who is rumoured to be interesting a host of top clubs in Europe.

The 29-year-old joined Kaiserslautern from Arminia Bielefeld in 2010 and has been linked with a move away following the club's relegation.

Kirch would be the third new arrival to the Signal Iduna Park, with the capture of Marco Reus and Leonardo Bittencourt already confirmed for next season.
