O'Neill has yet to open talks but it appears to be only a matter of time before he does after admitting that the player is back to his best.
"I haven't spoken to Stiliyan or his agent about anything. All I will say is this is the best he has ever played," O'Neill revealed.
"He is consistently playing well and I am so pleased for him. He got a great ovation coming off on Sunday and that is a testament to the way he has been playing.
"His confidence is very high and we are starting to see the Stiliyan I knew at Celtic."
