It is clear that Sarri has helped Hazard reach a new level, allowing him to play with more freedom and in a team that dominates possession.
Eden Hazard continues to be unable to hide his love for Real Madrid and, after leading Chelsea to victory over Southampton, the Belgian left the door more than ajar for Los Blancos with some interesting comments.
While Alvaro Morata's return to form has been a welcome boost ahead of the second global break, Eden Hazard has been the man to watch as the Belgian has been in terrific nick ever since the season began. He is still young so I think he is a good player for the future with Chelsea.
'The gap with City was large and we are trying to close it, but it's very hard in just one season'. I don't want to say: 'Yes, I am signing a new contract, ' and then I don't end up signing. We have got the players who have achieved that success before, and we believe we are capable of doing that.
"We are enjoying playing well and scoring goals". No mistakes at the back. "So, we just need to find a good solution", he summed up.
Sarri has challenged Hazard to aim to score 40 goals, which the 27-year-old thinks might be a tough total to reach, with 19 strikes being his current best in west London. Sometimes in my head, I wake up in the morning and think I want to go. When I can pass, I pass.
"I want the best for myself but also for the club [Chelsea] as they have given me everything". "Sometimes I think I want to stay".
It's no secret that playing for Real Madrid is Hazard's childhood dream.
Chelsea had the final word, though, as the irrepressible Hazard sent Alvaro Morata clean through and the substitute chipped the ball over McCarthy. "They missed big chances and then we have had a bit of luck for our first goal, but we controlled the match in the second half". "No, that's the truth".
"If tomorrow we are losing games then the speech will be different".
Barkley's goal and assist completed a memorable few days for the midfielder, who has just been recalled to the national squad for the games against Croatia and Spain. He is very good. He jokes a lot. It is not like if I go I am happy and if I stay that I am unhappy. He is a amusing guy but he likes to work.
The Blues have now won nine of their 11 games across all competitions this season, with league draws against West Ham and Liverpool the only blights on their record, BBC reports.
