Bayern Munich manager Jupp Heynckes will not reveal the reason he keeps rotating his squad but insists he will continue to do so, as the club have made their best start to a Bundesliga campaign.
Bayern's 2-0 win at Schalke on Saturday means they sit top of the league, having racked up four wins from four games, scoring 14 goals and conceding just two in the process.
Heynckes' policy of rotation this season continued at Gelsenkirchen as he made three changes to his starting line-up, bringing Mario Mandzukic, Luis Gustavo and Thomas Muller in for Claudio Pizarro, Javi Martinez and Franck Ribery.
And the Bayern boss was coy over his decisions, while also stating that €40 million signing Martinez was not dropped due to an ego problem.
"I am not willing to explain why I change the formation," he said. "It's not about egos, everyone needs to be on the bench at some point."
Martinez, 24, who replaced Mandzukic for the last 20 minutes, also revealed that he had no problem with being benched.
"The coach has told me I have to be patient and take one step at a time," he said. "In Bilbao I nearly missed a complete month of training and now it takes training and time to get used to the team."
Bayern take on Wolfsburg on Tuesday and the Spain international is unsure as to whether he will start due to the strong competition for places in the squad, which he believes to be a good thing.
"I don't know if I'll start. I have to train hard and try to get better," he added. "We have very good players in every position, including deep midfield where we have Bastian [Schweinsteiger], Luiz [Gustavo], Timo [Anatoliy Tymoshchuk] and me. That's good for the team."
Bayern also have Toni Kroos, who has been pushed forward into the attacking midfield position this season, at their disposal. He is one of the few players not to have faced the chop so far.
And Kroos, 22, seems to have taken a big step forward this term, having already scored three goals as well as playing a dominant role in Bayern's Champions League win against Valencia.
But Bayern director of football Matthias Sammer believes the Germany international can do even better.
"Toni has been handed a great talent. He needs to find the incentive. He needs to understand that voraciousness himself," he said.
