Chelsea winger Kevin de Bruyne struck for Belgium in their victory over Serbia in their World Cup qualifier.

New Blues boss Jose Mourinho was set to be in the stands for the tie.

The 21-year-old, who played behind Aston Villa striker Christian Benteke, waited just 13 minutes before opening the scoring with a neatly-taken header in Brussels.

De Bruyne and compatriot Thibaut Courtois, who played in goals for Belgium, are both unsure of their future at Stamford Bridge since Mourinho took charge last week, but the pair looked in good shape as the hosts dispatched their group rivals.
