The talented 21-year old winger comes out of contract this summer and the Seasiders are desperate to secure his services to ward off a potential move abroad or to the Premier League.
"We get compensation if he goes abroad, but I think it's more likely a domestic club will make an offer in January," Oyston told BBC Radio Lancashire.
"It's down to Tom and his father whether we choose to sell or keep him until the end of his contract.
"We have offered him a new contract. It's very fluid, there's nothing definite and I certainly shall not start speculating. Who knows what will happen, but it's an interesting situation."
