Jack Rodwell has not played a first-team game since September

Sunderland have offered to cancel Jack Rodwell's contract after their highest-paid player asked to leave, Sky sources understand.

The cash-strapped Championship side are willing to cancel his £70,000-a-week deal and let him leave for free.

However, the 26-year-old and his agent are yet to respond to the club's offer as they decide their next steps.

Sky Sports News understands the player had hoped to negotiate a pay-off but has been made aware Sunderland cannot afford such an agreement.

Rodwell has started in a winning Sunderland team only once in nearly four years

Cancelling his contract would mean Rodwell would walk away from future earnings of over £5m, and Sunderland would, in turn, waive receiving a transfer fee.

Sunderland signed Rodwell from Manchester City for £10m three years ago.

The 26-year-old has only featured in three matches this season, and he has only once been on a winning Sunderland side in a match in which he has started.

He was the only Sunderland player not to have a relegation clause in his contract, meaning he has been earning more than double of any of his team-mates, despite being consistently injured.

Sky Sports News understands there is a feeling within Sunderland that Rodwell could be doing more to make himself available to play as they battle at the foot of the Championship under Chris Coleman.
