Chelsea manager Frank Lampard knows his side must get positive results in their coming Champions League games.
Despite chances to win the match and a missed penalty, the Blues suffered a 1-0 home loss to Valencia in the first game of the group stages.
It is a tough blow for Lampard, who knows they must get three points in their next away games at Lille and Ajax.
He said the following to Chelsea's official website after the Valencia game: "The reality of losing the first game at home makes the rest of the games more important, particularly when they come next back-to-back away from home [Lille and Ajax].
"We need to have a strong focus on getting a result in one of those games now.
"It's still a group I think teams will take points off each other because all the teams are strong."
