Centre-backs - David Luiz (Chelsea) and Mamadou Sakho (Crystal Palace)
PSG signed David Luiz in the summer of 2014 from Chelsea for £50m which was a record fee for a defender at that time.
Luiz played 89 games for PSG in two seasons, scored 8 goals and won seven trophies before returning to Chelsea on transfer deadline day in the summer of 2016.

The Brazilian was named in the Ligue 1 Team of the Year in his two seasons at the club and in 2016/17, he was named in the PFA Team of the Year after an impressive season which helped Chelsea win the league title.
Mamadou Sakho was a first-team player at PSG long before the arrival of the new owners. Sakho is a product of the PSG academy and made his first-team debut in September 2007. Aged 17 years and 8 months, Sakho became the youngest ever captain in PSG history, a record he still holds.
After the takeover, Sakho remained the club’s captain but in the second half of the 2011/12 season, he lost his place in the side due to poor form and the arrival of Thiago Silva in the 2012 summer, Sakho's game time reduced even more.
Sakho moved to Liverpool in the summer of 2013 when Brendan Rodgers was the manager but fell out with Jurgen Klopp and was eventually sold to Crystal Palace for whom he still plays.
