17 Stillian Petrov
An absolutely incredible player and a major presence in our team for the whole of his time here.
People say he left too early; this is the era when players give us two seasons before they get moved on.
He gave us seven full seasons and played over 300 times for the club in that time.
What a footballer he was, and he remains a true Celtic man to this day. His battle with leukemia showed what he was made of off the pitch. We already knew what he had on it; he had everything. He will never be anything but welcome at Parkhead.
