19 Georgios Samaras
Seven seasons. Major trophies. Massive performances.
A player who never once hid, who never once gave up, who never shirked his responsibilities.
I loved him. I was a fan before it became fashionable because this was one of those rare players who gave 100% no matter if he was playing on the biggest stage or on a wet weekend in Brechin.
He played 249 times for us. He scored 74 goals.
He was a fantastic servant to Celtic, and yet remains one of the most under-rated players on this list.
