Nicolas Anelka joined Chelsea from Bolton on this day in 2008.
The France striker, then aged 28, completed a move to Avram Grant’s side for a fee of £15million.
The Blues had been looking for extra firepower to help them overcome the loss of Didier Drogba and Salomon Kalou to Africa Cup of Nations duty.
“Chelsea are a big club. I have proved that I can score goals at the top level and I can do the same for Chelsea,” said the much-travelled Anelka, who counted Arsenal, Real Madrid, Paris St Germain, Liverpool and Manchester City among his former clubs.
“I want to tell the Chelsea fans that I see this as a great opportunity and an honour to play for Chelsea and I will not disappoint them.
“Chelsea is the team I really wanted to join and I hope this will be the last club that I play for.
“I am delighted everything has been sorted out. This was a fantastic opportunity that I couldn’t turn down.
“I am really looking forward to working with Avram and Chelsea’s style of football really suits my game.”
Anelka would go on to score 59 goals in 184 games for the Blues and his time at Stamford Bridge saw him win the Premier League and two FA Cups.
However, he saw his effort saved in the decisive spot-kick in the 2008 Champions League final penalty shootout defeat by Manchester United in Moscow.
Anelka left Chelsea in January 2012 when he moved to Chinese side Shanghai Shenhua and he had further spells at Juventus and West Brom before finishing his career with Indian club Mumbai City.
