The central defender was signed in August 2004 from Coventry City before heading out for a loan spell at West Ham. He was recalled in the December and made his debut as a substitute in attack at Aston Villa, later departing for further loan stints at Southampton and Norwich City.
Calum returned to the Spurs fold in December, played his part in the clinching of the reserve league and received his rewards this Easter with another substitute appearance up at Everton followed by his first start against United.
It was an experience he enjoyed, but his pleasure was tempered by the fact that we were unable to add to our points tally against the Carling Cup holders.
"Like I said to the lads, what a game to make your home debut in," he reflected afterwards.
"Obviously we are disappointed with the result, but I thought we played well and created a lot of chances.
"They hit us with a good counter-attack, which they are good at, then there was a sloppy second goal from our point of view. We got back in the game early in the second half and deserved at least a point."
Like in his debut at Villa Park, Calum ended up in attack, but he points out it was not only due to the need for a goal.
"When you haven't played in the Premiership all season it is hard. I got a bit of cramp so they told me to go up front and cause a bit of havoc," he added, before recalling that his central defensive partnership with Michael Dawson is not an unfamiliar pairing.
"I have played with him for England under-21s and I think he was cramping a bit as well after missing two games. On the whole I think the lads can be pleased with the performance, but the main thing was the result and we didn't get it.
"Everyone knows what we are trying to achieve and, if we keep playing the right way and keep the ball on the floor, we will always create chances. Unfortunately we didn't take them this time."
It was a long time in the making, but Calum Davenport finally got to make his big White Hart Lane entrance against Manchester United on Monday.
