Only the woodwork denied Chelsea when Alonso's low shot hit the far post, while Hazard clipped a shot narrowly wide as the Blues' frustration mounted.
Maurizio Sarri came in at Stamford Bridge quite late into the summer transfer window - owing to a standoff between the Blues and their former manager Antonio Conte. However, how the former England global can help a struggling United defence considering his age is anyone's guess, as we have already seen that another 30-something Mourinho favourite from Chelsea, Nemanja Matic, has been in bad form and has been slammed by teammates and pundits alike.
The France international's form has also been regularly questioned, having only scored his first goal of the season at the 12th attempt during a Europa League clash with BATE Borisov last weekend.
Gana told evertontv: "Yes, of course, the training is changing, we train hard and you can see it in the way we play: we try to play football". We have to be careful because in the last three matches you are right. "We have a lot of physios at Chelsea, so I just start with more treatment".
"I don't think it is a physical problem, in the second half we played at another speed, intensity, so I don't think it is physical, maybe mental".
"The average points of City and Liverpool is very high".
"I think that, during a championship like the Premier League, this can happen to any team, a match like this".
With Chelsea ramping up the intensity in the second half, Everton became understandably stretched as the game went on and had to rely on all 11 players to keep their focus and discipline.
