Southampton have reportedly had an offer in the region of £9.5m for Argentine left-back Marcos Rojo rebuffed by Sporting Lisbon.
Rojo, who starred for Argentina at this summer's World Cup, has been strongly linked with a move away from Portugal this summer.
Despite interest from Chelsea, Southampton are believed to have made the first official offer as they prepare to replace Luke Shaw.
However, according to O Jogo, Sporting have rejected the opening offer of £9.5m.
It is understood that the Saints will return with a new bid this week.
