Borussia Dortmund have announced that they have sacked head coach Peter Bosz after less than six months in charge, replacing him with former Cologne boss Peter Stoger.

The 54-year-old Dutchman arrived in the summer as the long-term replacement for Thomas Tuchel at BVB, having enjoyed terrific success with an Ajax side he led to the final of the Europa League last season.

However, things have not passed nearly so smoothly in Germany, and Saturday’s 2-1 home defeat against Werder Bremen, which has left Dortmund seventh in the Bundesliga standings, 13 points behind leaders Bayern Munich, was the final straw.

Stoger has now been appointed as Bosz’s replacement for the rest of the season, having been sacked by Cologne at the start of December. The 51-year-old spent four seasons in Cologne, helping Koln qualify for Europe for the first time in 25 years.

Bosz’s statistics are poor, with only eight victories from 24 competitive matches, 10 of which ended in defeat.
