German football matches have been stopped regularly in recent weeks as part of an ongoing protest involving throwing tennis balls, gold chocolate coins and apples onto the field to voice their anger against foreign investment in the German top-flight. The fans are demanding an end to a controversial plan from the league to sell a stake of future revenue to a private equity investor. The campaign to stop it was given a boost this week when prospective buyer Blackstone dropped out of talks. However, there remains one more leading candidate in the shape of CVC Capital Partners.
