Bayern Munich forward Thomas Muller has insisted that he and his teammates are not getting carried away despite their impressive start to the season.

The Bavarian giants have won all eight of their Bundesliga matches and two out of three games in the Champions League.

"The coach (Jupp Heynckes) keeps on reminding us that we have not achieved anything yet and keeps us grounded," Muller told Bild.

"We all realise that we haven't won the league yet, regardless of our perfect start. With the last two seasons in mind, we will definitely not get complacent."

Bayern will host Bayer Leverkusen at the Allianz Arena in the Bundesliga on Sunday.
