Tottenham paid Southampton more than £8m to sign Dean Richards in September 2001 and he made an instant impact at his new club.
The former Wolves defender scored 15 minutes into his debut against Manchester United - in a match perhaps best remembered for United turning a 3-0 half-time deficit into a 5-3 victory at White Hart Lane.
He was unable to feature in Spurs' run to the League Cup final that season, having appeared for the Saints earlier in the competition, but he was a regular fixture in the Tottenham side until the end of the 2003-04 campaign.
Sadly, Richards was forced to retire in March 2005 on medical advice, having suffered from headaches and dizzy spells for some time beforehand.
A club statement at the time said Richards had "undergone extensive tests" which "produced strong, conclusive medical evidence that it would be harmful to his long-term health to continue in the sport".
In all, Richards, who died exactly 15 years ago today, played 81 games for Spurs and scored four goals.
