Petr Cech says Chelsea's Champions League match in Bucharest tomorrow night is a must-win game.

Blues are already trailing in their group, having been defeated at home a fortnight ago by Swiss side Basel.

Now they travel to the Romanian capital - where they were beaten 1-0 six months back, in the first leg of an ultimately successful Europa League tie.

“We need to get three points back,” said the Chelsea number one.

“If you lose one game in the group, it's not a drama if you win the other games.

“We need to get 11 points to make sure we qualify for the next round. It doesn't matter how and in which order you get them.

“We obviously put ourselves under a bit of pressure because we gave Basle three points. In the end we have five games left and if we win them all, we will go through.”
