When Celtic snapped up Beram Kayal from Maccaibi Haifa in 2010, the Israel international impressed massively, with reported interest from Liverpool and Manchester United less than six months into his stint in Glasgow.
Yet since an ankle ligament injury sustained in December 2011, Kayal hasn't quite been able to hit the same heights, and has suffered a number of niggling injuries during his time at Celtic Park.
Now a move to the one of the Premier League big boys couldn't seem further away, with the 26-year-old starting just twice under new manager Ronny Deila.
Recent speculation has suggested that a return to Maccabi Haifa could be on the cards, and the Daily Record are today reporting that Kayal has told a close adviser that he will demand a move next month.
"I want to leave Celtic during the transfer window," Kayal allegedly said. "I feel my time is up and it would be better to go in January rather than hang on until the end of the season."
It's believed that Celtic would need a £500,000 bid in order to part with Kayal, which could possibly attract the interest of his former Bhoys boss Neil Lennon, who may want more additions at Bolton Wanderers.
Still, a move back to Israel seems most likely, with Kayal desperate to recapture the form that saw him linked with a move to the Premier League.
With the likes of Stefan Johansen, Scott Brown and Kayal's compatriot Nir Biton ahead of him in the pecking order, it's clear that Kayal's future lies away from Celtic Park - and allowing him to leave in January is the best solution for all involved.
