Bakircioglu (pictured) could be heading out of Twente and The Tukkers have already identified their summer target.
Diba has a troubled relationship with NAC Breda coach Ernie Brandts and is likely to depart the Rat Verlegh Stadion.
"I just cannot get on with Ernie Brandts," Diba said in the past. "I only communicate with the assistants, so it is better for all parties that I leave."
The 24-year-old has a clause in his contract that allows him to depart for a transfer fee of é¼1.5million (£1million).
However, Vi.nl reports that Diba may be able to move on for as little as é¼500,000 (£340,000), alerting Twente to his possible availability.
