The Belgian attacker wore the Ligue 1 champions' outfit after Wednesday's defeat at Parc des Princes
The Belgium international featured for the full 90 minutes in the Blues' defeat at the Parc des Princes on Wednesday evening, before exchanging shirts with one of the PSG players.
He then found his way on to the Canal+ cameras for a post-match interview wearing the Paris Saint-Germain jersey.

Hazard's action has caused uproar among the Europa League holders' fans on social networks, with a picture of the winger in a PSG kit doing the rounds on Twitter.
The 23-year-old was heavily linked with a move to the Parisians before eventually leaving Lille for Chelsea in the summer of 2012.
PSG have since been linked with Hazard on more than one occasion, although his current club are adamant that the attacker is not for sale. The Belgian has a contract with Chelsea until June 2017.
