Coates would not be surprised if Pulis told him Owen was on his list of transfer targets when he returned from his post-season holiday.
Coates told The Sentinel: "Tony is away at the moment, but that is one we could discuss when he gets back. He was interested in him previously.
"Michael Owen has been a fantastic player and I can see why Tony might be interested. But that will be very much a judgement for the management to make."
