Hazard didn't touch him, he kicked the ball out from underneath him, and the ball "man" played a blinder, even putting his arm up and shouting "ref"! Clearly been watching too many overseas players play acting.
From the BBC report on the game...
" On the sidelines communication seemed a major issue, as Pochettino does not speak good English. Strength and conditioning coach Nick Harvey appeared to be helping to pass on instructions to the players. Towards the end of the game it appeared to become a signficant problem."
