"I spoke with him during the week, he understood", Sarri added.
Chelsea took its fans to hell and back throughout February.
Yet barely six minutes had later Craven Cottage erupted when Calum Chambers drifted unmarked to the back post and scored from a Ryan Babel cross following a corner kick.
Exploiting the space left by Fulham's creaky defence, Hazard and Willian both tested Rico with low drives soon after the restart.Even with the perennially inconsistent David Luiz left on the bench, there were still moments of uncertainty from Chelsea at back.
