Didier Drogba admits his dismissal in Moscow last season probably cost Chelsea the Champions League.
Drogba's red card in the Champions League final against Manchester United in Moscow last May prevented him from taking a penalty in a dramatic shoot-out.
John Terry missed the spot-kick that would have earned Chelsea their first Champions League triumph and when Nicolas Anelka also missed, Manchester United went on to make it a hat-trick of European triumphs.
Drogba has more regrets about losing the final than being red-carded.
"You have a lot of regrets when you go to the final and lose it," said Drogba.
"I have more regrets about losing the final than being sent off. But the team was affected by the sending off and we lost on penalties."
