Chelsea manager Jose Mourinho is reportedly keeping tabs on Benfica forward Lazar Markovic and was rumoured to be a spectator in the Red Star Stadium during Serbia’s World Cup qualifier against Croatia last night.

The 19 year old signed for the Portuguese side from Partizan Belgrade this summer and has already started showing immense talent on-field.

Markovic had caught the eye of top European clubs after making his International debut at the age of 17 years and had subsequently also come on the radar of the Blues. However the west Londoners failed to make a timely move for the Serb and Benfica succeeded in landing him at the Estadio da Luz.
