Manchester United boss Sir Alex Ferguson is reviving his interest in Bayern Munich fullback Willy Sagnol.

The Sun says Ferguson is keeping a close eye on the France right-back and could move in the January transfer window.

Fergie rates the Frenchman highly and United need cover in that position.

Sagnol, 30, is returning to fitness after four months out with a leg injury. Crucially, he could be available for Champions League duty, as he has not played in Europe with Bayern so far this season.
