#2 David Luiz
David Luiz endured an interesting first spell at Stamford Bridge which saw him winning the Champions League. But losing concentration and committing mistakes too often led to his departure to Paris Saint-Germain.
When new Chelsea boss Conte signed Luiz at the transfer deadline for hefty money, it was termed as a 'panic move'. But the Brazilian silenced his critics courtesy of an impressive season, propelling Chelsea to the league title.
He played the sweeper role in Chelsea's back three, which was perfect for his ability to spray long balls and to read the game defensively. His partnership with Cesar Azpilicueta and Gary Cahill reaped dividends as Chelsea kept the most clean sheets in the league.
Luiz limited his lapses of concentration and kept strikers like Zlatan Ibrahimovic, Romelu Lukaku and Harry Kane scoreless in league encounters.
His solid campaign was rewarded with a place in the PFA team of the season. Truly a perfect homecoming.
