Chelsea goalkeeper Petr Cech was left upset with their Europa League first-leg defeat to Steaua Bucharest.

Cech fears Chelsea's failings in front of goal could come back to haunt them next week.

He said: "We ended up with the worst result and the disappointing thing is we haven't scored.

"We had the better chances and I hardly had to make a save all game.

"I can't tell you whether it was a penalty or not. I just saw Ryan running with their guy and suddenly he was on the floor.

"We have made it hard but 1-0 is not a scoreline which can't be overturned."
