Check out all the latest Chelsea transfer news and gossip from today.
Brazilian defender David Luiz left Chelsea earlier this summer because he found Jose Mourinho 'unbearable' to work with.
That's according to Spanish newspaper El Confidencial - who claim the former Benfica star's £50 million switch to Paris Saint-Germain had an ulterior motive.
The huge money offered by PSG was deemed by many as too good to turn down, for a player whose defensive capabilities have been called into question on numerous occasions in the past.
However, Luiz was incredibly popular in the Stamford Bridge dressing room, and it's not yet clear what impact his departure will have on first-team squad harmony moving forward.
Mourinho welcomed some of his Blues players back for the start of pre-season training this week, as preparations for the new campaign begin to gather pace.
A number of senior stars are still on international duty at the World Cup this summer though, including Luiz's Brazilian compatriots Ramires, Oscar and Willian.
