The club have responded to an 11-game winless streak which has seen them drop into the bottom three ahead of the season's finale.
Oral delivers promise
"FSV Frankfurt have always had a place in my heart and I've always followed them since I worked here," said Oral, who was FSV's coach between 2006 and 2009. "I can promise one thing: we are going to put in an honest 90-minute shift in Düsseldorf. It's up to us and we will do all we can to ensure FSV remain in Bundesliga 2 next season."
FSV have thanked Möhlmann for "three and a half years of good collaboration," while saying they felt compelled to make a change "after analysis of the recent run of games without a win." FSV dropped into the bottom three after losing 3-1 at home to 1. FC Union Berlin on Sunday.
