Didier Drogba and Michael Ballack believe Chelsea have the quality to go all the way in the Champions League.

Avram Grant's side comfortably beat Olympiacos 3-0 on Wednesday night to move into the quarter-finals of this year's competition and record their second win in a row, after they thrashed West Ham 4-0 on Saturday.

Drogba now feels there is no doubt that the Blues have bounced back from their Carling Cup final defeat to Tottenham.

"I hope so, it's hard because sometimes we have difficult moments like the Carling Cup where we didn't play, but we were great on Saturday against West Ham,' the Ivorian told Chelsea's official website.

Ballack, who played for the second game in succession with Lampard in midfield, was delighted to reach the last eight.

'We are happy we are in the next round and played a good game from the start. It was good to score early and that was very important today,' he said.

The German midfielder, however, admits he would rather avoid playing another English side at this stage of the competition.

'It's always good if in the Champions League if you can play teams from other countries, but if every English team goes through you will play each other, so we will see,' he said.

'We have a good team, and have a possibility to reach the final or win the Champions League. We have to think from game to game and show that we can win the Champions League. There are more games, but we have the experience.'
