Chelsea boss Jose Mourinho couldn't hide being alarmed after his side dropped two points against Rosenborg 1-1 at home in the Champions League group opener on Monday. “The history of the game was simple, we had 20 chances and scored one goal. So maybe we need 40 chances to score two and 60 to score three," said the Portuguese coach. "Our 20 chances were not enough to score two goals. It is not my strikers it is my team. My team played against a team that in my opinion did its game. Like smaller teams do when they visit the better teams, they come here to defend and are organized,” added the Blues coach. Miika Koppinen broke the deadlock in the 24th minute but Ukrainian striker saved Chelsea's day and scored the equalizer in the 53rd minute. It's first goal for the London-based side in three matches. The absences of Ivorian Didier Drogba and skipper Frank Lampard are obviously having a huge impact on the team's offensive power. Valencia are on top of the group with three points after beating Schalke 1-0. Chelsea and Rosenberg trail the Spaniards by two points.
