The new German signing believes he can stake a claim for an immediate first-team berth and has revealed that Spurs did make an offer for him before he moved to west London
The 23-year-old agreed to sign for the Blues in April after they agreed a fee in the region of £6.5m for the talented attacking midfield player. Marin will officially join the club on July 1 when the transfer window re-opens.
He told Spox.com: "I am sure that I will play for Chelsea. Why? Because they took me to London. The management has convinced me. It is a top-team!
"They have won the Champions League. The club, the scouting, the management, they have often observed me and they are convinced that I can help the team."
Marin is highly thought of across Europe, and the diminutive playmaker - who was born in Yugoslavia but has won 16 caps for Germany - confirmed that north London rivals Tottenham also made an offer to try and secure his services.
He added: "There was also an offer from Tottenham - yes, that is right."
