Chelsea boss Roberto di Matteo is delighted with the new creativity of his midfield.
The manager, while acknowledging the blossoming relationship between the two attackers, believes there is yet more to come from the duo.
"Hazard and Mata have found a very good understanding from the start," he says. "Some players just click naturally and are on the same wavelength.
"They haven't trained together for a long time because of the summers they had. That's why in five or six weeks' time, when they've had a bit more time together, they will be able to work even better on the pitch."
