There are probably enough reasons for Lorenzo Amoruso to be excluded from this list altogether, but he should be recognised for how he overcame a serious injury and controversy both on and off the pitch to end his six-year spell by winning the domestic treble.
Amoruso missed the majority of his first season at Ibrox with an Achilles tendon injury and made his debut in a Scottish Cup semi-final with Celtic, which Rangers won 2-1. For much of the first part of his stint in Scottish football, though, the Italian struggled for consistency and was targeted by the club's supporters and faith had been lost in him by Dick Advocaat.
However, Amoruso was rejuvenated under Alex McLeish, who arrived at the club in December 2001, and for the final 18 months of his time in Glasgow, he was superb as Rangers recovered from Celtic's dominant 2001-02 campaign to win the treble the following season.
He won the Scottish Player of the Year award that year, but his crowning moment would come when he scored the winning goal in the 2003 Scottish FA Cup final, which would represent his 228th and last appearance in a Gers shirt.
