But Warburton, who has moved up from his role as sporting director to take over as manager, said: "If he does, they will go on our terms.
"But the fact is we have looked after the players, there are a lot of boys here on three-year contracts which is unusual in League One but we recognise their talent and want to keep them here.
"So for us it's very important that if they do come in then of course there's a price, but it's our price and not the buying price."
