Coloccini left St. James' Park after eight years to return to Argentina on Tuesday.
Coloccini played 263 times for the Magpies in eight years in England after joining in 2008, and has experienced plenty of highs and lows during his time on Tyneside.
He suffered relegation in his second season at the club, but was a cornerstone of the side that won immediate promotion back to the Premier League to following year, being named in the 2010 Championship Team of the Season.
Two years later he was selected in the PFA Team of the Year as he arguably established himself as one of the most impressive central defenders in England.
However, his career began to nosedive in recent years, and his time as a Magpie came to an end in sad fashion with the 34-year-old not having made an appearance since February amidst accusations from supporters of the Argentine no longer having the passion or commitment to fight for the club's cause.
Though Newcastle fans were pretty split on his departure, injured goalkeeper Rob Elliot, who has played alongside Coloccini for five years, made his own feelings clear with a message to the defender on Twitter on Tuesday afternoon.
The goalkeeper wrote: "Am lucky enough to [have] played with this guy but even more privileged to call him my friend #iwantcurlyhairtoo."
Supporters may feel that Coloccini has somewhat tainted his legacy at the club, but it is clear that the former leader will be missed by many of his teammates.
