The Blues take on Podolski's Arsenal at the Emirates Stadium and Marin is well aware of the quality the former FC Cologne man possesses but he is sure Ivanovic can do the job in the London derby.
"I know Lukas from the national team and at the beginning it was all new to him but now he is doing well and has scored a few goals," Marin said.
"But we have a very good defence and Branislav will do very well at right-back. It will be hard for Lukas to play against him.
"Of course I am very confident (we can keep Podolski quiet).
"I know Branislav very well, he is one of the best defenders in the Premier League. I am not scared about this."
