Manchester United are reportedly preparing a dramatic £40million bid to sign Aston Villa goalkeeper Emiliano Martinez before the transfer window closes.
The Argentina international, who turns 33 early next week, has re-emerged as a target for United despite earlier doubts about his wages and temperament.
According to Fabrizio Romano, United made a fresh approach to Villa and Martinez's representatives over the weekend.
Talks over Royal Antwerp's Senne Lammens remain ongoing, but Old Trafford chiefs want cover in case the £20m move for the Belgian falls apart with less than 48 hours of the window remaining.
