Kevin de Bruyne is fully committed to Manchester City's Treble push this season.
De Bruyne will be key tonight for the second-leg of their Champions League semifinal against PSG.
And a source, speaking with HLN, has revealed De Bruyne has been determined to stay fit and healthy throughout the season.
"If one of the children is ill, he sometimes dares to come and sleep at the club of his own accord," said the source.
"Nothing upsets him in the run-up to a match. Ice cold. Nerve level below zero."
