3. Marko Marin
Everyone remembers Marko Marin during his time in the Bundesliga with Werder Bremen and he was being compared to Messi, yes, the Argentine. Marin signed for Chelsea and his career has gone down the drain, the German has been sent out on loan endlessly and now plays for Trabzonspor. He is only 26-years-old but his talent seems to have gone down the drain already.
