Wolverhampton Wanderers chief executive Jez Moxey has revealed that the club tried to bring Robbie Keane back to Molineux in the January transfer window.
The 29-year-old Republic of Ireland forward began his career with Wolves, but opted against a return to head to Celtic on loan from Tottenham Hotspur until the end of the season.
Moxey revealed: "We asked about Robbie Keane and I spoke to Tottenham on a couple of occasions. We knew what his wages were and we'd have done that, but he wasn't going to come to us.
"Almost every loan at this level also comes with a really hefty fee, but we'd have pushed the boat out to get Robbie. In the end, though, the opportunity to fulfil a lifetime's ambition to play for Celtic was too much of a pull."
Keane scored 29 goals in 88 games for Wolves before leaving for Coventry City in the summer of 1999.
