Petr Cech believes it is vital Chelsea get off to a good start in tonight's Champions League match against FC Basel.
Chelsea were knocked out of the Champions League in the group stages last season as they failed to progress from a group including Juventus, Shakhtar Donetsk and Nordsjaelland.
The Czech Republic international wants an improvement in his side's Champions League displays.
Speaking exclusively to Chelsea's official website, Cech said on last season's Champions League campaign: "When you look back, if we won that game against Juventus having been 2-0 up, the two points would have made a difference.
"But that this the way, there are no ifs and buts, you have to get more points than the other teams and we didn't do so."
"Last season we didn't do well, that was the simple thing. If you do well you obviously qualify, if you don't do well then you can't qualify and those games we played last season in the group stage we were not playing well enough to win games.
"This is why Shakhtar and Juventus ended with more points than us, that was it.
"You have to make sure you win games at home, you win games away, and the group stage gets tougher and tougher every year because the teams are getting quality players as they want to improve every year, and you need to make sure you are ready."
Cech also revealed that he would be keeping a close eye on Viktoria Plzen's results - due to his ties with the Czech Republic side.
"It is an exciting time for them and they did well to qualify," concluded the former Viktoria Plzen trainee.
"For the people there it is great to see a big team from England and from Germany with Bayern Munich coming to their town."
Chelsea manager Jose Mourinho may decide to rest Cech for tonight's Group E clash against FC Basel, with Mark Schwarzer still waiting to make his competitive debut for the Stamford Bridge outfit.
