“Marcus Berg’s departure this week to Panathinaikos on a free transfer was confirmation that the Swedish striker has been a huge Bundesliga flop. However, he is not the first (and won’t be the last) player to cost a club millions of euros, not perform and leave for a small fraction to another club, or even for nothing at all. This is not a list of the most expensive transfers or even the biggest transfer flops; this is a list of the worst bits of business that Bundesliga clubs have made.” Bundesliga Fanatic – Part 1, Part 2
