WFC: Chelsea's Marin expects big things from Bradley

SEATTLE – Fans (and journalists) love the summer transfer window. It’s always great column and podcast fodder, as we all try to figure out who’s the next big player getting a new address.

One of the bigger transfers on the European front was winger Marko Marin moving from Werder Bremen in the German Bundesliga to Chelsea FC. The 23-year-old is expected to make his Blues debut Wednesday night against Seattle (9:30 pm ET; ESPN2) in the first game of the 2012 Herbalife World Football Challenge.

“The hope is to improve by playing with high quality players,” Marin said at a press conference on Tuesday afternoon. “Of course, I want to show that I will do my best.”

Marin’s name may be familiar to Yanks who’ve combed through the boxscores of games featuring American Exports over the years. He was one of the stars of Borussia Mönchengladbach from 2007 through 2009, his time there overlapping with US national team midfielder Michael Bradley.

Bradley, like Marin, has made a big summer move. He’ll now be suiting up for AS Roma of Serie A after transferring from Chievo Verona.

By Marin’s reckoning, it’s a good fit.

“He is a really good player, playing central midfield,” Marin offered. “We had a good time together. Then he went on loan [to Aston Villa], and I went to Bremen, but I know he will have a good time [with Roma].”
