Barnsley have hit back at former Everton manager David Moyes over the transfer of John Stones.
The young defender was famously the last signing the Scottish boss made as Blues manager before heading to Manchester United that summer.
Many consider it among the best he made during his spell at Goodison Park, with £3million a steal considering how Stones has developed over the last few years.
He is now one of the brightest young talents in England and indeed Europe, with fees upwards of £30milion now being talked about for his services. English clubs Chelsea and Manchester United have been linked with moves for the player, as have European clubs Barcelona and Real Madrid.
However, in an interview with Goals on Sunday, Moyes claimed that the club actually paid around £1.25m for his services.
"I laugh when people say we paid £3 million for John Stones. It was £1.25 million," he told Sky Sports' Goals on Sunday.
"It was in the January and the last signing of the window. We were trying to bring a striker in that we needed but we didn't have the money."
Now, Barnsley have hit back in response to those claims, saying that Moyes never played any part in negotiations for Stones in the first place.
"Given the categoric nature of the assertion made, it is incumbent on Barnsley FC to correct such a statement when it is markedly and unequivocally wrong and yet is made by someone that the public might think is authoritative on the subject," a club statement reads.
"This is particularly the case since he has cited the same erroneous fee on previous occasions also. David Moyes played no part in any negotiation with Barnsley FC concerning the transfer of John Stones, which may explain why he is mistaken as to the fee paid."
So, who knows what Everton truly paid for Stones. Regardless of what both Barnsley and Moyes have to say, I think we can all agree that the Blues got a superb deal in any regard, even despite his struggles this season.
