Chelsea v Cardiff City: 5 Talking points

#4 The center-back partnership of Luiz and Rudiger seems to be getting better

Chelsea FC v AFC Bournemouth - Premier League

A lot of eyebrows were raised when Sarri opted for the out-of-favour David Luiz alongside Antonio Rudiger at the heart of defence. The duo have taken time to settle in together as partners, but seem to have now added solidity to their game.

Although both of them are world-class center backs, a few of Chelsea's goals so far have seen a lot of fingers pointed at Luiz for his lapse in concentration and lack of communication. In this game though, they looked more comfortable at the back.

Both of them were astute in terms of their positional game. They set themselves up well along with the others during set-pieces. They stood firm, won aerial duels, passes around safely and put up a fine shift at the back. Apart from the victory, this is something to smile about for the Blues' fans.
