West Ham joint-chairman David Sullivan has denied claims by former England manager Sam Allardyce that Enner Valencia's 2014 move to the Hammers involved third-party ownership.

But speaking about the allegation, West Ham joint-chairman Sullivan insisted Allardyce was wrong as he did not know about the full financial details of Valencia's move to England.

He told The Sun: "Valencia's economic rights were wholly owned by Pachuca when we bought him.

"Sam is wrong. But he didn't know much about the actual transfer deal other than wanting the player.

"We have not broken any rules on third party ownership."
