There was no clause in the deal that took John Stones to Everton which would give the Reds any money should the defender from Thurlstone play for England, the Chronicle understands.
Although Barnsley will command a large sell-on fee from any future transfer, sources close to the club have confirmed that there is no clause in the agreement with Everton, brokered by former director Don Rowing in January 2013, hat provides a payment to the recently relegated Reds from Stones' England debut, should it happen.
Chief executive Ben Mansford did not comment on the clauses in the deal but added: "It is a very well-made contract and we are bound by confidentiality not to talk about it. All I will say is that John has done phenomenally well and he is a credit to the club, his family and our academy."
Former Penistone Grammar pupil and Oakwell academy graduate Stones was named on the standby list for Roy Hodgson's England World Cup squad on Monday. He will attend the pre-tournament training camp in Portugal and, should Phil Jones' shoulder not heal by June 2 or one of the other central defenders get injured, he will be called into the full squad for the competition in Brazil.
Clubs such as Chelsea are known to be monitoring the progress of Stones – who does not turn 20 until May 28 – and the Reds will be entitled to a sizeable percentage of any fee paid to Everton. The original transfer fee paid by Everton is understood to be £3m.
