Roy Keane signed for Celtic in 2006 and he was certainly a huge name in Scottish football.
The Irishman made his home debut against Kilmarnock on 14 January 2006, and was deployed as a centre back next to McManus.
Prior to the match, he emerged from the tunnel to see this giant display by the Jungle Bhoys welcoming him to the club.
Celtic won the match 4-2, maintaining their position at the top of the league and Keane would go on to win an SPL medal with the club.
