Hannover are keen to tie their star striker to a new deal, but the player's agent Jim Solbakken has said that there will be no "hasty decisions".
"We are going to carefully consider the future," Solbakken told Bild.
"Mame is feeling good being at the club. There is no need to hurry into talks or to make hasty decisions as Mame is under contract until the end of next season."
Diouf has hit 13 goals in 25 appearances in all competitions this season for Hannover.
