Bayern Munich have reacted furiously to the news that Netherlands international Arjen Robben will be sidelined until October.
The 26-year-old former Chelsea and Real Madrid star missed the opening games of the Dutch team's World Cup campaign because of a hamstring injury but was rushed back to action as he helped his country reach the final in South Africa.
However, tests made by the German side have found a tear in the hamstring that was not properly diagnosed earlier.
"It is a clear tear," said Bayern club doctor Hans-Wilhelm Muller-Wohlfahrt. "I find it irresponsible that this was not diagnosed accurately and that Arjen has played with it. I offered several times to help with the diagnosis but was not called."
Bayern will now seek compensation from the Dutch federation (KNVB), with chairman Karl-Heinz Rummenigge saying: "Of course, Bayern Munich are very angry. Once again we must pay the bill as a club after a player is seriously injured playing for a national team."
