When it comes to value for money there can be few as good as Tore Andre Flo, who arrived at Chelsea in the summer of 1997 as a £300,000 signing from Brann Bergen in his native Norway.
Three seasons later, with 50 first team goals to his name, he departed in a £12 million deal to Rangers and a reputation as one of the best finishers in the game.
Tore scored as a sub on his Chelsea debut, a 2-1 defeat to Coventry, and went on to regularly make an impact from the bench as he helped us to FA Cup, League Cup and Uefa Cup Winners' Cup successes, as well as bagging a hat-trick at White Hart Lane in a 6-1 victory over Spurs in late 1997, an achievement fans still approach him about to this day.
The lanky striker also helped us qualify for the Champions League for the first time in 1999, and scored eight times in that campaign, including three against Barcelona as we bowed out in the quarter-finals.
Hugely popular at Stamford Bridge, Tore still regularly comes to watch games, and returned to the Premier League with Sunderland in 2002. He also played under former-team-mate Dennis Wise at Leeds before hanging up his boots in 2009.
