Sarri reckons the midfield match-up will decide whether the Blues or hosts Manchester City go home with all three points.
“Technically, they're the best midfield in Europe, so it will be really very difficult to be in control of the match.
“It's right that the match is there [in midfield] more than in the strikers.
“But it's wrong to say you stop City by stopping Fernandinho or Chelsea by stopping Jorginho. It's wrong for both, because they are able to play if you stop Fernandinho and also we're able to play if you stop Jorginho.
“We have options. Maybe they have more options than us, because of course they have worked on this for three seasons."
