Signed by Spurs for a fee that could have risen to £4 million, Calum Davenport was immediately loaned out to West Ham United ... much to the annoyance of Coventry City, who wanted the player back on loan until the end of the season.  His performances for the Championship team received rave reviews and the deal was done so that he could continue training with Tottenham and they could keep an eye on his progress with the East London side.

Calum made his debut for Spurs three months after signing at Aston Villa, coming on as a substitute for the last seven minutes of the game ... playing as a centre forward !!

On his return at Christmas 2004, he was sent out on loan again to Southampton for the rest of the season, making a limited amount of appearances as the side struggled and were relegated at the end of the season.

During the summer of 2005, he had the opportunity to join Reading on loan, but chose to stake his claim for a place in the Spurs team and he had also had the responsibility of captaining the England Under-21 side.  However, to get first team experience, Davenport was loaned out to Norwich City playing alongside former Spur Gary Doherty and while the Canaries would have liked to make the signing permanent at the end of the deal, as the central defender had once more impressed, but they were unable to afford Tottenham's asking price.  While there, he had an eventful spell, scoring against his former club, Coventry City and got sent off against Luton Town.

Ironically, for the next year, Calum enjoyed something of a run in the Tottenham side.  His height added to the back line and although he should have been more dangerous at set-pieces, he only recorded one goal in a Spurs shirt.  A good footballer, who was comfortable on the ball and keen to move up-field with it, Davenport looked the sort of player Spurs might use a lot, but with King and Dawson ahead of him, he would rarely be the regular first choice.

Having spent more time on loan than actually at the club, it was perhaps not too much of a surprise that in the January transfer window of 2006, he left to join West Ham United, where he believed he would get more on-pitch time, despite their perilous league position.  Spurs seemed to have recouped the fee they paid for him receiving £3 million for his services from the Upton Park club.

Failing to find a regular starting position in the Irons' line-up, Calum went on loan spells at Watford, where he suffered a bad back injury and when he recovered the following season, the defender went out on loan again to Sunderland.

Davenport was almost put out of football altogether when he was involved in a stabbing incident at his mother's house, which turned out to be his sister's boyfriend, who stabbed him in both legs during a family argument.  The perpetrator was sentenced for actual bodily harm and Calum had to appear in court for an attack on his sister, who claimed he had bitten her in the same incident.  The player was charged with the offence, but after a hearing, he was cleared of the offence.

In the summer of 2010, he was training with Nottingham Forest and Leeds United, before signing with United Counties side Wooton Blue Cross in an attempt to get fit again for a return to professional football.
