Manchester United are planning a bid for Benfica defender Antonio Silva.
United are prioritising Silva's signing and haven't ruled out paying his 100m buyout clause.
Sky Deutschland's Florian Plettenberg is reporting Silva now tops United's defensive shopping list, though any deal will wait until the summer.
United are already working on Silva's management team, with talks underway.
But the fact that United are in the process of signing a new defender most likely means they're also planning to sell a senior player.
