The Dortmund utility man caught the headlines for the wrong reasons recently but the 68-year-old insists he could be vital to Joachim Low's plans in Brazil.
Franz Beckenbauer believes Kevin Grosskreutz is crucial to Germany's World Cup plans despite recent controversy surrounding the 25-year-old's behavior.
The Borussia Dortmund man's place in Joachim Low's squad has been cast into doubt after he was caught urinating in a hotel lobby after a night out in the wake of his side's 2-0 defeat to Bayern Munich in the DFB-Pokal final on May 17.
Beckenbauer, however, believes the incident - which also saw the defender involved in a dispute with another hotel guest - should not detract from the defender's importance to the squad for this summer's finals.
"Of course Grosskreutz must go to the World Cup,” the 68-year-old told Bild. "Grosskreutz is the type of player that you can rely on as a coach. He always gives the maximum amount of effort and he is what we need in Brazil.
"Grosskreutz has of course done something that you do not do. One does not urinate in a hotel lobby. But, have we not all been there and done things that we have regretted afterwards?"
Germany coach Low must submit his final 23-man World Cup squad prior to June 2.
