Kiltie began his footballing career at Galston when he was just a young boy.
Greg signed a senior contract with Kilmarnock shortly after his 16th birthday and made his debut a few months later in May 2013.
The local lad appeared 5 times for Killie during the 2013/14 season before suffering an injury which kept him out of the closing stages of the season.
The tricky winger has represented Scotland at U16 and U17 level and played a key role in Scotland's qualification for the UEFA U17 Championships which took place in May 2014.
He has played at every level internationally for Scotland from U15 to U19.BACK
