The Brussels side lost 4-2 at lowly Kortrijk on Saturday with centre-back Kompany accepting blame for all four goals.
Former Belgium captain Kompany has since come under heavy fire from pundits back home.
"In the coming international break a coach would normally have two weeks to work intensively with his squad.
"But Kompany will be off with Belgium to play San Marino and Scotland - before having his testimonial game in Manchester.
"Some people like to be busy, but they can become too preoccupied.
"Kompany should think about this. There are limits to everything.
"If another centre-back had made the mistakes he made he'd have been criticised - and Kompany would have dropped him for the next game.
"Of course Kompany shouldn't retire from playing - but he has to make sure something like this doesn't happen again.
"If he is honest as a manager he can't be happy with himself as a player."
