Arsenal and Liverpool are both keeping close tabs on Lee Cattermole's situation, skysports.com understands.
The Wigan midfielder had an outstanding maiden campaign at the DW Stadium following his arrival from hometown club Middlesbrough last season.
Cattermole also shone whilst on international duty with Stuart Pearce's U21s over the summer as he helped England to the final of the European Championship.
Now his former boss Steve Bruce, who moved to Sunderland earlier in the summer, is desperate to sign him again.
Having lodged two bids for Cattermole already this summer and had them rejected, Sunderland are reportedly ready to test Wigan's resolve with a £10million offer.
Wigan supremo Dave Whelan has been quick to dismiss Sunderland's interest in the player - but propositions from two of the top-four could be a different matter.
Manchester United prised Antonio Valencia from Wigan earlier this year, and now they could face a similar battle to try and keep Cattermole - should either or both Arsenal and Liverpool make concrete offers.
One snag for either Arsenal or Liverpool could be that they are unlikely to want to go as high as £10million, which Sunderland are ready offer.
