Marko Marin declared Chelsea have the squad to win the Barclays Premier League and defend the Champions League after finally making his debut for the club.
Marin got his first taste of competitive action in Tuesday night's Capital One Cup thrashing of Wolves almost five months after agreeing a £7million move from Werder Bremen.
He said: "If you are to win the Premier League and Champions League, you need a lot of quality players. 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."
Unlike Chelsea's other summer signings, the Germany midfielder elected to join them before they ended their agonising wait for Champions League glory and while their participation in this season's competition remained in serious doubt.
The 23-year-old, who officially become a Blues player when the transfer window opened on July 1, then watched as the likes of Eden Hazard, Oscar, Cesar Azpilicueta and Victor Moses all followed him to Stamford Bridge.
