Chelsea vs Barcelona: 5 memorable moments

#2 Iniesta scores last-gasp in a high-tempered 2009 semifinal

Iniesta celebrates after scoring a late goal

This particular game between the sides remains one of the most controversial ever in the competition's history, and memories of that fateful night in Stamford Bridge still pricks the Chelsea hearts.

Riddled with dubious decisions, the Blues had as many as four legitimate penalty appeals overlooked which left the home team and the fans alike, really hot under the collar. And as Chelsea were distracted by the rage over the indecisiveness of referee Tom Ovrebo, the Blaugrana wielded the hammer in the deciding minute.

Messi was found in a difficult position to score, so the Argentine cut back for Iniesta who was completely unmarked, and the midfielder whacked an effort into the top corner to equalize and send Pep Guardiola's side into the finals on away goals rule.

Furious with the erroneous officiating, Didier Drogba pelted expletives at the referee post the game that eventually got him a four-match ban from European games by UEFA alongside Jose Bosingwa, whereas Chelsea too were fined £85,000 on grounds of misconduct.
