3-4-3 may have become virtually synonymous with Chelsea since their 13-game-winning run after switching to the system last season, but the west London outfit are by no means a one-system team.
Indeed, Antonio Conte tweaked his formation slightly in midweek to mastermind a stunning win over Atletico Madrid in the Champions League, employing a three-man midfield while putting Eden Hazard up top alongside Alvaro Morata.
We saw a similar setup against Tottenham Hotspur at Wembley last month when Chelsea also claimed a 2-1 victory away from home against a team lauded for their defensive strength, on that occasion Willian occupying the gap between a solo striker and a five-man midfield.
Although Chelsea are playing at Stamford Bridge this weekend, Manchester City represent the kind of opponent that it makes much more sense to try and nullify with shape and structure than simply attempt to outscore in an open game.
