The German midfielder stepped out with the Blues for the first time since his summer move from Werder Bremen in the 6-0 Capital One Cup win over Wolves last night.
After getting his first game time with Chelsea, Marin is now looking forward to achieving success with a very talented group of players.
"If you are to win the Premier League and Champions League, you need a lot of quality players," said Marin.
"Chelsea have changed a lot since last season and now we have more attractive and offensive players.
"We hope that there are a lot of goals in this team because then it is more difficult for the other teams to play against us."
