Shaw's current deal expires next summer and the length of his proposed new contract is still to be finalised.

The 23-year-old England international joined United from Southampton for £27m in 2014.

Shaw's progress has been disrupted by poor form and fitness issues, limiting him to only 75 appearances, but he has been a regular for United this season.

His recent performances have also earned Shaw, who scored against Leicester City in United's 2-1 win on the opening day of the campaign, a recall to the international set-up.
