The Blues lost 1-0 against Inter Milan at Stamford Bridge, something that secured Inter Milan a 3-1 aggregate triumph.
“We didn’t play the way we wanted,” he told Sky Sports.
“I think Inter stopped us playing the way we wanted and that’s what made the game difficult for us.
“It is a difficult result and now we are going to have to focus on the league and the FA Cup.”
Drogba was sent off for a foul on Thiago Motta in the closing stages of the game.
“It is difficult to take because, yes I stepped on his calf, but I don’t think I deserved this red card,” said Drogba.
“But it is something that happened in the game. The most important thing is that we are out of the competition.”
