Dortmund make Burki signing

The Bundesliga side said in a statement that the 24-year-old ‘was one of the most reliable goalkeepers in the Bundesliga last season.’

Burki, who has made two appearances for Switzerland, played all 34 of Freiburg’s games this season but couldn’t prevent them from slipping to relegation on the final day.

The arrival of the former Grasshopper Zurich keeper casts a doubt over the future of 34-year-old keeper Roma Weidenfeller’s future, who has just one year remaining on his contract.
