The Londoners play Mourinho's United in the first Premier League game after the global break on Saturday. But the timing of the comment, in the context of United's left-wingers struggling for form and confidence, seems odd.
Nonetheless, Mourinho has been no stranger to criticising his own team and again appeared to damn his players with faint praise when asked why they have been unable to replicate the second-half performance against Newcastle over 90 minutes.
Hazard scored 14 top-flight goals during that campaign but was one of a number of Chelsea's high-profile players to reportedly fall out with Mourinho the following season.
Mourinho is hoping to win at Stamford Bridge for the first time as United manager and, more importantly, start climbing the table after a disappointing start.
"Even today we don't have every player back, so it is a bit odd when you come from the worldwide week, but I think the feelings of the last match remain, so the players are fine, are happy and focused". Yes, it bothers me.
However, the 20-time English champions came from 2-0 down to rescue a 3-2 win over Newcastle ahead of their trip to Premier League title challengers Chelsea FC. "Yeah (it has an affect on them)".
Mourinho doesn't believe that will happen, but insists the two had a good relationship. "Every day of my life at Stamford Bridge, the fans were always behind me".
"He's a player like the others; no player is bigger than the club and, if I'm happy with his work, he plays", said Mourinho in late-September. "I am fresh, very fresh".
