United boss David Moyes is desperate to add to his defensive options in the summer, with current left-back Patrice Evra likely to follow Nemanja Vidic out of the club.

The Scot had hoped to bring Everton's Leighton Baines to United, but failed to agree a deal with the Toffees for the England international both in the summer and the January transfer window.

With Baines having committed his future to Everton by signing a new four-year contract at Gooidson Park late last month, Moyes will now put all of his energy into striking a deal to secure Shaw.

Saints owner Katharina Liebherr assured manager Mauricio Pochettino and the club's supporters that star players Adam Lallana, Jay Rodriguez, Rickie Lambert, Morgan Schneiderlin, James Ward-Prowse and Shaw would not be sold.

But according to ESPN, a January offer, in the region of £22.5m made by United for Shaw, 18, is still on the table with Moyes eager to secure the services of the England under-21 international in front of Chelsea.
