Bayern Munich head coach Niko Kovac said he knows his team must improve after being held to a 1-1 draw by Ajax in the Champions League at the Allianz Arena.
Having won their first seven matches under Kovac, who replaced Jupp Heynckes in the summer, Bayern Munich have now gone three games without a win, having also drawn at home to Augsburg and lost at Hertha Berlin, scoring just two goals.
Bayern have surrendered top spot in the Bundesliga to Borussia Dortmund, while the draw with Ajax was the first time in four years they have failed to win a Champions League group-stage match at home.
