Turning to the green for a second spring, Sutton linked up with Celtic in a £6million move and, as if by magic, resurfaced as the man he once was.
Mattea Kerzhman, 2004-05
Chelsea crowned with Premier League glory for the first time, while Kay Dayman failed to excel on his way to the title.
He had arrived in the Premier League from Dutch side PSV Eindhoven for a transfer fee of £6 million and could have replaced Hasselbaink, however, he failed to recreate the Dutch style in his Premier League campaign, picking up just four goals in 25 games before being transferred to Atletico Madrid the following year.
Karidi Bolaruzzi, 2006-07
Chelsea in order to break the curse of the No. 9 jersey or ease the pressure on the front line, £ 9 million to bring in Boras Bollaerts from Hamburg, but the "ogre" has not been able to get rid of the fate of the substitutes, injuries have also limited his performance at Chelsea.
Steve Sidwell, 2007-08
Sidwell came from the Arsenal youth academy and joined Chelsea on a free after four years at Reading, only to make a handful of appearances under Jose Mourinho and was eventually sold to Aston Villa with the No.9 shirt.
Franco Di Santo, 2008-09
Argentine winger Di Santo joined Chelsea for a transfer fee of £4million but has been consistently missing out on goals and despite a loan spell at Blackburn, his performances continue to fail to impress.
Fernando Torres, 2011-15
Torres' 2012 Champions League semi-final strike made the £50m transfer fee look good value for money, but his career at Chelsea has not been as good as it could have been, with just 45 goals in 172 games.
Radomel Falcao, 2015-16
Falcao, who played for Manchester United, joined Chelsea as a major adventure, however, due to fitness and adaptation issues, he made just 12 appearances for the Blues, scoring one goal.
Alvaro Morata, 2017-18
Morata, who joined Chelsea for £60 million with 15 goals in his debut season, was unable to get out of the shadow of the No. 9 gown and scored just five Premier League goals the following season, eventually joining Atletico Madrid.
Gonzalo Iguane, 2019
Sarri had high hopes for Iguaín, however the Argentine star did not perform as well as expected in the Premier League, with his overweight weight and speed disadvantage manifesting itself at Chelsea, and eventually returned to Juventus.
