Sporting Lisbon defender Marcos Rojo is refusing to discuss his future despite continued speculation linking him with a move away from Estádio José Alvalade this summer.
The Daily Express reports how the 24-year-old has attracted interest from Manchester United, Chelsea, Liverpool and Southampton, and is believed to be available for transfer for around £13 million.
Rojo rose to prominence following a series of impressive performances for Argentina at the World Cup, and has been heavily linked with a Premier League switch before the close of the transfer window.
Red Devils boss Louis van Gaal is in desperate need of defensive reinforcements at Old Trafford, and Rojo's ability to operate at both centre-back and left-back make him an attractive proposition for Manchester United.
Brendan Rodgers is also known to be on the lookout for a new left-sided defender as negotiations with Sevilla's Alberto Moreno continue to drag on. A transfer to Anfield is likely to appeal to the South American star, with the option of playing Champions League football.
However, Jose Mourinho has been mooted as an admirer of Rojo too, despite already negotiating a deal to bring Brazilian full-back Filipe Luis to Stamford Bridge. Chelsea might therefore prove to be the most attractive option should the player have his sights set on a move to England.
Southampton are the only club said to be willing to meet Rojo's valuation though, so a switch to St Mary's must not be ruled out at this stage either.
Regardless of the recent speculation, Rojo is reluctant to be drawn into a debate when it comes to his next destination, insisting that his current focus remains on Sporting Lisbon and preparations for the new campaign with Marco Silva's side.
"Have I played my last game for Sporting? I don't know," he was quoted by Sky Sports in an interview with Portuguese newspaper O Jogo.
"The thing I want to think about the least at the moment is whether I will stay or go."
Interest in the player isn't exclusive to England, with Serie 'A' giants Napoli also monitoring Rojo's situation closely, as Rafael Benitez considers an attempt of his own to lure the World Cup star to Stadio San Paolo ahead of the 2014/15 campaign.
The versatile stopper might not be giving anything away when it comes to transfer negotiations at present, but it looks increasingly likely that his future will be served away from the Primeira Liga.
