Bruno de Carvalho has hailed Marcos Rojo's transfer to Manchester United as the second best in the club's history.
Sporting Lisbon's president was quick to address the deal during a seminar on 'How to run a successful football club' at the Soccerex convention in Manchester. He believes that the deal was perfect for Sporting.
Carvalho was quoted by Record as saying: "It really was a wonderful deal. A sale of a central defender for €20m is a very good deal. It was the second best sale ever for Sporting."
He did not confirm which deal he considered to be the best for Sporting, but it is easy to see why he ranks Rojo's move to Old Trafford so highly.
Not only did Sporting receive €20 million from Louis van Gaal's team, but they were also allowed to take former star Nani on loan for the season. Not only that, but Manchester United also agreed to pay Nani's £120,000-a-week wages, essentially adding another £7 million to the transfer fee.
The deal that saw Rojo become a Manchester United player did not run all that smoothly, however. The Argentinian was co-owned by a third party. Doyen Sports are currently in the process of legal action against Sporting for what they deem to be insufficient payment after the transfer fee was received.
Doyen are demanding 75 per cent of the transfer fee, including an extra €5 million for what they consider the value of Nani's loan deal brings to the equation. If they are successful, it will take away a huge chunk of the transfer fee.
However, Carvalho openly challenged Doyen's claims in another talks, suggesting the company's contract was invalid. Doyen attempted to force the transfer to Manchester United, which Carvalho claims nullified the terms of the original agreement.
"It was invalid," he said. "That contract means manipulation. It means engagement with the management [of the club]. It's not a contract. It's null.
"Without a doubt it was bringing manipulation to the game and that is not good.
Carvalho transfer talks
In other Sporting news, Carvalho is reportedly using the convention to hold transfer talks for another Sporting star, William Carvalho.
The holding midfielder was strongly linked with a move to Manchester United, Chelsea and Arsenal in the summer but failed to seal a move away. However, it is widely accepted that the holding midfielder will eventually move on from the Primera Liga.
Representatives from all of the Premier League's big clubs will be in attendance with Arsenal appearing the keenest to iron out a deal in principle.
