Kayal agrees new Celtic contract
The 23-year-old Israeli has been in negotiations for a number of months after looking to improve his terms following an impressive debut season.
"I feel at home here and I want to be at the club for a long time," he said. "The fans have been magnificent and I want to thank them all for their support. I will do everything for the club and the manager to achieve success."
Kayal has made 40 appearances for Celtic, scoring two goals, and was one of their key players last season despite missing much of the campaign through injury.
But he fractured his wrist in the 3-2 defeat by Inverness Caledonian Thistle that cost Celtic the title in May, and missed the Scottish Cup final win over Motherwell.
