"It's something we'd been expecting and now know we know for sure," Dufner explained. "Even though it was clear to us what Mame's intentions were, we still needed a definitive decision so that we could start planning for the new season."
"We'll remember him as an extraordinary striker, who was one of Hannover 96's key players and a fan favourite," Dufner continued. "Therefore, we'd like to thank him for his whole-hearted commitment to the club and wish him all the best for the future on a personal and sporting level. He'll always have ties to the city of Hanover, and not just because his young daughter was born here."
Senegal international Diouf, who sat out the last nine games of the 2013/14 season through injury, netted 26 goals in 57 Bundesliga games following his January 2012 transfer from English Premier League outfit Manchester United FC, as well as a further two in the DFB Cup and seven in the UEFA Europa League.
