Manchester City boss Pep Guardiola has hinted at long-term concerns over Kevin de Bruyne's fitness.
The Belgium ace has missed large chunks of the season due injury.
Guardiola says De Bruyne will be missing again for Monday night's clash with Leicester City.
"I do not know about Kevin. For next Monday he is not available," conceded Guardiola.
"I do not know what's going to happen in the future."
