SuperSport are now believed to be putting together a package to tie down the in-form Gabuza to fend off any rival interest.
"They want to keep him," says a source close to the club.
"He adds a lot of value to the club and is a great character to have around in the dressing room.
"The club loves Gabuza and he is enjoying himself here," the source adds.
SuperSport United have also previously confirmed that they will be willing to listen to offers for midfielder Tebogo Mokoena next season.
