Skysports.com understands that Sunderland have launched a triple bid on Manchester United by making offers for Wes Brown, John O'Shea and Darron Gibson.
Sunderland are busy in the transfer market with Jordan Henderson set to finalise his move to Liverpool.
Now Black Cats chiefs have made their own moves and have lodged a bid of around £12million for the trio.
And it is believed United are ready to do business for the trio of players who have all come through the ranks at Old Trafford.
Defender Brown, 31, midfielder Gibson, 23, and utility man O'Shea, 30, will now decide whether they want to make the switch to Wearside in the coming days.
