Why Caldo will be a massive miss for Newcastle
He arrived here as some bloke who used to play for Tottenham and Aston Villa and left as a figure that helped write an important chapter in the history of Newcastle United.
Colin Calderwood left the club's Benton base with his head held high after playing a crucial if under-stated role with United in the last 18 months.
For a bloke who has been the big chief of both Nottingham Forest and Northampton, Calderwood somehow managed to perform his duty as first team coach without treading on Chris Hughton's toes and maintaining the respect of United's senior players.
The man who once marked Ronaldo had the respect of the first team pool at United because he'd been there, done it and got the t-shirt.
Like Hughton, he didn't big himself up and when it was needed most, with spirits down at the start of the 09/10 season, he managed to get the players laughing again.
In June 2009, after Newcastle fans and players had endured a tough summer, he made sure the job of promotion was focused on by the lads.
It was Calderwood who broke down the Championship season into segments and set the players smaller goals to be reached by the end of each month and each international break.
This was done by using his experience of the Football League having won promotion with Forest and the Cobblers and when you consider how much Newcastle needed a bloke who knew his way around the highways and byways of the Football League last summer, Calderwood's part in the Championship title winning season becomes crystal clear.
In Calderwood, Chris Hughton has lost not only a good friend but also an excellent coach and a great man manager.
Calderwood liked to keep a low profile around the media but did do the odd interview, and unusually in football, when he did opt not to do an interview, he'd always explain why and his reasons always seemed to make sense.
He can be replaced of course but whoever comes in as Hughton's number 2 will have a hard act to follow.
His final request to me as a United man was to make sure he was allowed to thank the fans, the club and the city for his time here and he admitted whenever he thought of Newcastle, he'd always think of his time here with a smile.
All the best Colin, it's been emotional!
