One man missing from tonight's big Champions League clash between Chelsea and Atletico Madrid is a legend of both clubs.

Diego Costa was released from his contract at Atletico Madrid earlier this year and is currently a free agent.

The Brazilian-born Spain international is a hero of both sets of fans and is sure to be watching the first-leg of tonight's round of 16 tie.

At Chelsea, Diego Costa won two Premier League titles and here we have a fantastic tribute and highlights of his time at Stamford Bridge.
