Jupp Heynckes: 'We must keep our feet on the ground'

Bayern Munich manager Jupp Heynckes has insisted that his players must keep their feet on the ground, despite an impressive start in the Bundesliga.

Heynckes's men have won eight out of eight so far and are nine points ahead of reigning champions Borussia Dortmund.

The 67-year-old has warned his players against complacency ahead of their game against in-form Bayer Leverkusen tomorrow.

"They are in very good shape at the moment," he told reporters. "They play flowing, attractive football and are very skillful.

"We should be well-advised to keep our feet on the ground, approach it professionally and not rely on statistics."

Bayern will be without Arjen Robben for the game, which takes place at the Allianz Arena tomorrow afternoon.
