The TV deal means that very few PL clubs have to sell their stars for financial reasons now. Naturally, if bigger clubs want to buy one of their stars, there is a premium to pay, and that premium has grown. 5 years ago, for instance, Everton wouldn't have been able to afford to say no to £35m for Stones or Lukaku. Likewise, they would not have been able to outright buy Lukaku from Chelsea either. Times have changed. A club like Everton can now decide it is worth more to them to keep players like Stones and Lukaku than to sell them even for a large fee. You need to up the fee considerably, I think, to get them to take notice and consider a transfer.
