Celtic's new permanent manager Neil Lennon has confirmed his desire to bring Robbie Keane back to Parkhead.
The Republic of Ireland international spent the second half of the SPL campaign with the Bhoys on loan from Tottenham.
Keane proved his quality in Scotland with 12 league goals from 16 appearances, form that impressed Lennon.
Lennon has now confirmed he is looking to thrash out a deal with Spurs to secure him permanently, although he would not be gutted if they missed out on his signature.
It has also been suggested that Lennon might have to report to the club's board over signings, however, he has confirmed he will have the final say over fresh faces.
"I'd love to have Robbie Keane back here. It'll be his decision," said Lennon. "Financially it'll be a big decision for us if we can pull it off.
"He was wonderful. He made a massive contribution. Not only on the field. He's got those leadership qualities that I'm looking for. He has that quality that we've been lacking this year and a half or so.
"If it's achievable then why not? It's not the type of signing I need. I need to strengthen in all areas. If I can get that one extra special signing then I'd be delighted. If I can't then I won't be too disappointed because I have to build a team.
"I have to add, in certain areas, not just the mentality, but the quality. I am looking to bring in a few players with a bit more experience with a bit more nous and a better mentality than we showed last year.
"I'm going to make all the decisions, let's get this clear. There are no mixed messages. I'm making all the decisions regarding the football department. With other things I'll speak with the board."
