Chelsea coach Avram Grant admits he was disappointed with their performance in Tuesday night's 0-0 draw at Olympiacos.
"The result is okay, although you always want to win. A draw away is not a bad result but we didn't create a lot of chances and that was disappointing.
"It is not easy to play against Olympiacos. They are a very organised team. We will try to improve for the return leg."
Grant refused to confirm whether Lampard or Terry will start the Carling Cup final against Tottenham at Wembley on Sunday.
He said: "I need to tell the players first and not the media."
