Now he wants them to enhance his job prospects by securing an FA Cup win on Saturday.
Braintree were moments away from stunning National League leaders Salford City on Saturday.
Away from home, the bottom club were leading 2-1 until Rory Gaffney struck in the dying stages.
Hayrettin is caretaker after Bradley Quinton left the club ten days ago. He wants the job but always knew he would be measured on how the players reacted.
In charge when the club went down the year before last, he hopes to make up for lost time.
But chairman Lee Harding has revealed the club have had 120 applications for the role.
Hayrettin said: “It was a case of immense pride on Saturday, even if we didn’t quite hold on for the win.
“The players were absolutely superb, they were fantastic.
“We worked so hard and the boys showed courage against the best side in the division currently.
“Now we go to Barnet in the FA Cup looking to build on that and we will see where it takes us.”
