Paris Saint-Germain defender David Luiz has stuck the boot into Chelsea, claiming his former club will regret letting him and Frank Lampard leave.
The Sun reports how the Blues cashed in on the Brazil international earlier this summer when the Ligue 1 giants offered a mouthwatering £50 million for the 27-year-old.
Most Chelsea fans seemed happy to see the back of the eccentric South American stopper, who had a reputation for kamikaze defending during his time at Stamford Bridge.
Jose Mourinho appeared increasingly reluctant to pick Luiz at centre-back last season, after noting the player's carelessness in possession as too risky for the style of football he wanted to implement in west London.
So, when PSG came calling the Portuguese coach was happy to sanction the former Benfica star's sale, three-and-a-half years after he first arrived in England from Portugal in a €25 million deal.
His departure was one of a number of high-profile player exits at Chelsea over the summer, with veteran stars Lampard and Ashley Cole following Luiz out of the door on free transfers.
Blues legend Lampard has taken on a new challenge in the United States with new MLS franchise New York City FC, but will return to the Premier League on loan with Manchester City for the first six months of 2014/15.
Cole, meanwhile, opted to transfer to Italy, joining last year's Serie 'A' runners-up AS Roma for a tilt at the domestic title over there this season.
The acquisition of Brazilian left-back Filipe Luis from Atletico Madrid has gone some way to filling the void left by the ex-England international, but Luiz believes that the Blues are yet to replace either himself or Lampard, and feels the decision to part company will come back to haunt them.
David Luiz quotes:
"I have to believe that Chelsea or any team will miss me," he said. "I'm not arrogant but I'm confident in my own abilities.
"Paris paid a lot for me so they obviously believe in me — it is nice to be at a club where they really want you and where they show belief in you.
"I can only speak about my experience of playing with Frank [Lampard] and I still think he has lots to offer at the highest level. Not just because he is a great player — but also because of his experience in big games.
"I have as much chance of winning major trophies here as at Chelsea or any other club in Europe."
Whilst Luiz's departure was by no means a surprise, the decision not to hand 211-goal midfielder Lampard a new one-year deal stunned supporters, who had hoped the 36-year-old would be offered an extension like club captain John Terry.
It will be strange seeing the club legend run out in Manchester City colours this season, but fans must accept that his arrival at the Etihad Stadium only came about after he was let go having been deemed surplus to requirements at Chelsea.
