Sporting CP are said to have identified Pedro Goncalves' successor this summer.
The Portuguese club are well aware that Goncalves is likely to leave for a Premier League club.
Aston Villa are seriously interested in his signature, with O Jogo stating the club are already planning for life without him.
The source states that Sporting are assessing Famalicao's Ivan Jaime as a replacement.
While Sporting boss Ruben Amorim wants to keep Goncalves, the club did not qualify for the Champions League, which impacts finances.
Big offers from Premier League clubs are not rejectable for clubs in Sporting's position.
