Youri Tielemans warned Belgium against complacency ahead of their crucial World Cup qualifier against Kazakhstan in Group J.

The Red Devils sit top of the group with 14 points after their opening six matches, one ahead of second-place North Macedonia, who have played one more game.

Rudi Garcia's side will secure their place in next year's World Cup finals with victory in Astana on Saturday.

Kazakhstan, who have seven points from as many games, cannot finish in the top two, and were beaten 6-0 by Belgium when the sides met in September.

But Tielemans insists his team-mates cannot take their opponents – under the caretaker stewardship of Talgat Baysufinov following Stanislav Cherchesov's departure – for granted.

"Everyone expects us to win here comfortably, but that's not how football works any more," the midfielder said.

"Kazakhstan also have a new coach and might play differently. We have to adapt. We have no excuses within the squad. We just want to win here."

Even if Belgium fail to secure qualification on Saturday, they will have another chance to do so against bottom side Liechtenstein in Liege three days later. However, coach Garcia wants it sealed as soon as possible.

"It's certainly a topic of conversation within the group [qualification]. A World Cup is quite an experience," he added. 

"Hopefully, we'll get the job done [on Saturday], and then we can talk about it even more. Not playing at 100% would be a mistake, because I don't want to wait until Tuesday to qualify."
