Kayal arrived in Glasgow back in 2010 from Maccabi Haifa, and the Israeli international made an instant impact at Celtic Park, with a number of fine performances attracting the interest of Liverpool and Manchester United just six months into his career in Scotland.
Then just 22, Kayal showed plenty of promise for Neil Lennon's men, but has since been plagued by a number of injuries, particularly this season as he has made just eight appearances for the club - but he still harbours ambitions of playing for one of England's biggest clubs.
"In my first season at Celtic a lot of teams came to watch me,’ he said. "Kenny Dalglish, who was manager of Livepool, and Sir Alex Ferguson at Manchester United had communications with me. With a lot of teams interested, Celtic wanted too much money. Now, because of my injuries, the price is much lower but my dream is still alive and well."
Now 25, Kayal is evidently disgruntled with life north of the border, and criticised the standard and style of football played in the Scottish Premier League, suggesting that he will leave the club this summer if he gets an appealing offer from another team.
"There is a lack of technique, the football is played at a breakneck speed with power and intensity, and it doesn’t stop for a minute,’ added Kayal. "I’m not in love with this league. If someone comes up with an attractive proposition to Celtic and me, then I’ll go."
Both Liverpool and Manchester United are expected to be looking to add depth in the midfield this summer, but taking a risk on an injury prone player who had only succeeded in Israel and Scotland could be the last thing on the minds of managers Brendan Rodgers and David Moyes.
