James McFadden has signed a short-term deal with Motherwell until the end of January as he begins a third spell at Fir Park.
The 32-year-old former Scotland forward has been without a club since leaving St Johnstone at the end of last season.
He began his career with the Steelmen before returning for a second time in 2013 after spells with Everton, Birmingham and Sunderland.
Motherwell boss Mark McGhee told the club website: "Faddy has performed superbly well in training and deserves a chance here. It’s fair to say he’s not doing this for the money, purely a love of the game and a desire to help.
“I see him as a great character to have about the club - he’s a winner, he passionately cares about how this club performs and that sort of enthusiasm will, I think, help inspire some of the youngsters about him.”
McFadden, who is available for Saturday's game at Celtic Park, said: “I am delighted to be back - the club has always had a special place in my heart and I’ve always had a close bond with the supporters.
“I’ve been training hard - I feel fit. I’ve attended almost every game this season and I really believe I can help out. From my point of view, it obviously helps me get some game time."
