Today it was announced that the technical director Michael Emenalo, who has been working at London's Chelsea club since 2007, has decided to leave.
The team's newcomer Alvaro Morata recently revealed that former Nigerian national team member played a key role in his move to the English capital, but now the "aristocrats" have lost one of their key specialists.
At the same time, there are ongoing talks about internal disagreements with coach Antonio Conte, who today said he is unsure about David Luiz's future at the club.
"The decision to leave was very difficult, but I believe it is the right one for me personally, my family, and the club," Emenalo said.
"Over the past 10 years, I have had the privilege of working alongside some of the most talented people in the sports world and I leave incredibly proud of our achievements. I wish Chelsea the greatest success and look forward to witnessing many more triumphs for the club in the future."
Yesterday, the capital's footballers unexpectedly defeated "Manchester United" with a score of 1-0, bringing back excitement in the battle for the highest positions in the Premier League.
