Manchester United defenders Wes Brown and John O'Shea are delaying their move to Sunderland.
The Daily Star says Sunderland are waiting to hear back from Manchester United after tabling a £12m bid for O'Shea, Brown and Darron Gibson.
While Gibson is keen to move, O'Shea and Brown are waiting to see if there is interest from any other clubs.
Brown has also been linked with Tottenham and Everton.
