Former Leeds United captain Luke Ayling is set to be on the move again at Middlesbrough.
The fullback, 32, joined Boro last summer from Leeds.
The Sun says Ayling is a target for Sheffield United manager Chris Wilder.
Wilder is a fan of Ayling, who can play at fullback and centre-half.
And the veteran is set to leave Teesside as a free agent this summer, so making him an attractive proposition for Wilder.
