Here, we list all of Martin O’Neill’s Celtic signings made during his simply unforgettable time in charge at Parkhead.
He was the man who delivered Celtic’s first domestic Treble in 32 long years and instantly etched himself into the fabric of the club.
Martin O’Neill achieved this in his premier season in charge of the Hoops and would go on to win seven major trophies including three SPL titles.
He was also the first Celtic manager to reach a major European final since Jock Stein in 1970 but agonisingly lost to Porto in extra time of the 2003 UEFA Cup Final.
O’Neill is also remembered for his incredible recruitment – spending big in the 2000/01 campaign – which supercharged his success in the east end of Glasgow for a period of five years.
He has made 29 signings across his three spells in charge and below, 67 Hail Hail have listed them all including heroes such as Chris Sutton and John Hartson among others.
