Roberto Di Matteo issues Chelsea warning

Interim coach Roberto Di Matteo warns his Chelsea players that "nothing" has so far been achieved as they take a 1-0 away lead into the home leg of their Champions League quarter-final against Benfica on Wednesday.

Salomon Kalou's late strike gave the Blues a precious victory in the Stadia de Luiz, but the Italian reminds his players that an effort like the one produced to eliminate Napoli in the last 16 will be required.

Di Matteo refuses to discuss any ambitions to be the full-time Chelsea manager, instead wishing to concentrate on achieving "results".
