Carlo Ancelotti says it will take some time for him to come to terms with PSG's Champions League heartbreak against Barcelona.
The Blues hold a 3-1 aggregate lead ahead of Thursday evening's quarter-final second-leg meeting with the Romanians at the Luzhniki Stadium in Moscow, Russia.
And Moses, who scored Chelsea's second in the first leg, believes an early goal could kill the tie and ensure the west London club progress.
"We're here to try to win the game. They have good strikers and they will be in our faces from the start," the 22-year-old told reporters.
"We just need to get our noses in front and try to win the game. It won't be an easy task but we're looking forward to it. If we can score an early goal that will be great for us."
Meanwhile, talk over who will replace Rafael Benitez when the interim boss leaves Chelsea is of no concern to Moses.
"To be honest we have got a good manager here at the moment who has got good experience," Moses said.
"We are just taking each game as it comes, I don't think that it will affect me in any way.
"I just want to enjoy myself while I'm at Chelsea, concentrate on every single game that I am going to play."
Chelsea are also hoping to make a second successive FA Cup final when they meet Premier League champions Manchester City on Sunday.
"We just want to put the City game behind us at the moment, that doesn't come until Sunday," Moses said.
