BERLIN (Reuters) - Borussia Dortmund coach Peter Bosz arrived in Germany at the start of the season pledging attractive, attacking football but his time could run out as soon as Saturday if his side fail to beat bitter rivals Schalke 04 in the Ruhr valley derby.
Dutchman Bosz initially lived up to his reputation when Dortmund raced to six wins in their first seven league matches.
