#2 David Luiz
A player who has divided opinions throughout his career, David Luiz looks like he has finally run his race at Stamford Bridge. He has been a visible player for the team since he joined from Benfica in 2011 for £25.5m.
His attacking verve and commitment have made him a firm favourite with the Stamford Bridge faithful who constantly sing his praises. However, for Chelsea's coaches, it has been challenging working with the Brazilian international.
While he has all the attributes of a good defender; height, power, intelligence, aerial ability and so on, his propensity to switch off and make elementary mistakes has frustrated many a Blues coach.
This saw him being sold to PSG for a princely 50m in 2014. However, two years later, he returned to the club for £34m. He was great in Conte's title-winning side as well as in the UEFA Champions League triumph under Roberto Di Matteo in 2012.
He has entered into the last six months of his contract and while he has been good in patches under Sarri, it is clear that the old mistakes are still very present in his game. The club has a policy of not offering long-term extensions to over-30 players. As such, this is expected to/should be his last season in Chelsea blue.
