Delph has been desperate to repay fans for their support after injury-plagued past years.
He told the Birmingham Mail: "The fans have been great with me, they've been patient.
"I've been here four years now and I've been injured most of them. If I'm being honest, if I was a fan I'd probably be a bit frustrated thinking 'oh, when's he going to start playing'.
"All credit to them they've backed me all the way and it was nice to come off and hear the applause from the fans."
