The Dortmund man has admitted that it was not easy not to be involved in Brazil and is keen to fill Philipp Lahm's void in the team
The BVB man did not appear a single minute during the tournament in Brazil as national team coach Joachim Low preferred others in his position and Grosskreutz has admitted that it was not easy for him to play a bit-part role.
"I owe a lot to Schweinsteiger and I am grateful to him," the 26-year-old is quoted as saying by Kicker.
"He helped me out right from the start of the World Cup and always supported me when I didn't play.
"It was not easy to be a reserve player, but it is not about individuals at such a tournament. The World Cup was an amazing experience.
"I just tried to play my role for the team and contribute to the good atmosphere. And I always gave my all on the training pitch. That was important to me."
Grosskreutz is one of the candidates to replace Philipp Lahm at right-back following the Bayern star's international retirement and he's determined to show that he's up for the task.
"It will be a tense battle for the position of right-back and I will give my all to be in with a chance."
Schweinsteiger had to apologise to Grosskreutz's Dortmund after he was filmed chanting offensively about Bayern's Bundesliga rivals.
