The Blues currently top the league table ahead of their clash with Arsenal on Saturday, and drew their only European clash so far this season with Juventus.
No team has yet won back-to-back Champions League titles, yet Marin believes that his side can do that as well as winning the Premier League.
"If you are to win the Premier League and Champions League, you need a lot of quality players," Marin said.
"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."
Chelsea will face Manchester United in the last 16 of the Capital One Cup.
