In Germany, it is very rare that a player changes clubs for an extravagant sum. Players like Mesut Ozil and Nuri Sahin, for example, have recently been poached from the Bundesliga, the two costing a combined price of around €25 million (£21.5m). So, when Arsenal tabled an alleged €40m (£34.5m) offer for Borussia Dortmund playmaker Mario Gotze, they were expecting it to be sufficient.
