United are hoping to complete a £60million deal for Sporting Lisbon star Fernandes this week.
And part of the agreement could see Argentina centre-back Rojo return to Lisbon after he was frozen out by Ole Gunnar Solskjaer.
Rojo has made just three Premier League appearances this season.
However, Nicolo Schira claims Turkish giants Fenerbahce have thrown their hat in the ring for Rojo.
They can apparently match the defender's £80,000-a-week wages, which Sporting can't meet in full.
And should Rojo opt for a move to the Super Lig, United will be forced back to the negotiating table over Fernandes.
