The Bayern Munich midfielder believes the likes of Dortmund and Leverkusen are too inconsistent to challenge his side and wants to seal the title soon
The Bavarians sit 19 points clear at the top of the table after Sunday's 4-0 win over Hannover, which followed Borussia Dortmund and Bayer Leverkusen's respective losses to Hamburg and Wolfsburg.
And the Germany international believes both of his side's rivals lack the ruthlessness to sustain a serious title challenge.
"I'd sum up the teams behind us as relatively inconsistent," he told TZ.
"Particularly Dortmund or Leverkusen, who have lost a lot. [We want the title] as soon as possible."
Kroos went on to note that Bayern have started certain games slowly this season but says they are working to improve on it.
"Overall this is certainly a point on which we can improve," he said.
Bayern's next game is against rivals Schalke at the Allianz Arena on Saturday.
