Marko Marin believes Chelsea have a good enough squad to win the Premier League – and retain the Champions League.
The Germany star joined the Blues from Werder Bremen in a £7million switch this July, and made his competitive debut in the Blues’ 6-0 Capital One Cup win against Wolves on Tuesday night.
And the 23-year-old claims Roberto Di Matteo’s side are capable of challenging for honours at the end of the season – because they strengthened so well over the summer.
“If you are to win the Premier League and Champions League, you need a lot of quality players,” he 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."
But Marin claims Arsene Wenger’s side are yet to face a real test, like they will against the Blues.
"They have a good team but they lost Van Persie, who was the best scorer last season," he went on to say.
"I'm not sure they have played against a good team like us."
