His side failed to score for the third time in their last five Premier League games at Stamford Bridge, raising more questions about Chelsea's need for a top-class striker in the January transfer window.
And the 27-year-old says he couldn't pass up the opportunity to reunite with his former manager.
Paris Saint-Germain are claimed to be keen on signing the midfielder and some of the top names in the Premier League are also very much interested in getting their hands on him. "I think we need something different for characteristics", said Sarri. We have to try to solve the problem.
Due to this, there has been a general dependency on Hazard to produce the goods but he has still not managed to standout in every game which has partly contributed to the Blues' fourth position in the standings.
New signing Christian Pulisic won't join the club until next season, loaned back to Borussia Dortmund for the remainder of the current campaign.
Despite dominating against Leicester, Sarri's team were beaten 1-0 as they paid the price for lacking the incisive passing and movement needed to break down the visitors' obdurate defence.
