3 positive changes at Chelsea since Maurizio Sarri took over at Stamford Bridge

#2 The reemergence of David Luiz

Luis is once more an integral part of Chelsea's team

Ever since his 2011 arrival at Stamford Bridge, David Luiz has firmly established himself as a fan favourite, with his jovial nature as well as his tendency to leave everything on the pitch endearing him to the hearts of the Chelsea faithful.

However, the 31-year-old found himself frozen out of the first team picture towards the end of Antonio Conte's reign, with the Brazilian having fallen out with his Italian gaffer, with speculation linking him with a move away from Chelsea having seen his starting spot lost to Andreas Christensen.

Since Sarri's arrival however, Luiz has once more been thrust into the heart of defense, having played in 21 of Chelsea's 22 EPL matches thus far.

Luiz is a highly technical defender, which comes as a useful asset to Sarri's gameplan, as the former PSG man's efficient long range passing comes in handy to Chelsea breaking down high pressing defenses by bypassing the midfield and this was evident in Pedro's stunning goal against Newcastle earlier this season.

Dvaid Luiz is currently locked in a contract dispute with the Chelsea board, due to the club's rather abysmal policy of only offering one year contract extensions to players over 30.

Maurizio Sarri himself has come out in support of David Luiz continuing at the club, which is a sign of the premium placed on the defender by his gaffer.
