Bayern Munich goalkeeper Manuel Neuer has warned his teammates against getting complacent in the second half of the season.
The German giants are currently nine points clear at the top of the Bundesliga table and are also in the running for the Champions League and the DFB-Pokal.
"The problem is we are only halfway through the season," he told Bayern's official website.
"It means we have to stay very, very calm and always remember we still have a long way to go yet.
"It can all change very quickly: you sometimes lose a match unluckily due to silly goals, like the home meeting with [Bayer] Leverkusen in the autumn, for example."
Bayern will take on Stuttgart away from home in the Bundesliga on Sunday.
