All the transfer news and gossip from Stamford Bridge this morning.
Mata has joined Manchester United for £37.1 million overnight - while Essien is currently tying up a move to AC Milan after arriving on Friday.
Mata has thanked Chelsea on Twitter and admitted that he in fact planned a longer tenure with the Blues:
"Before last summer, my intention was to stay here for a long time; as long as the club wanted me to, and to keep winning trophies for Chelsea FC. This is how happy I was in the club and in the city.
"Things changed after the pre-season. From feeling like an important player, I started to experience some difficult situations and I felt unable to help the team to the extent that I wanted and was used to. Obviously, I fully respect the circumstances. Football is a team sport and it's not easy to play regularly in such a good squad.”
Mata had lost his regular starting place in the team under the services of returning manager Jose Mourinho. The Portuguese did not feel the Spaniard had the defensive qualities needed to play his style of football.
Meanwhile Essien has been speaking about his departure - suggesting that new Milan coach Clarence Seedorf convinced him to take the move:
“I joined Milan because of Seedorf. I spoke with him two days ago. Seedorf is a great man and I hope that he will also become a great manager.”
Chelsea boss Mourinho has already stated that the club will not be signing a striker in January - but it seems they are preparing a bid for a big name forward in the summer.
Indeed it is reported this morning that the club are willing to sell Romelu Lukaku to make room for Edinson Cavani.
The Uruguayan is said to be unhappy in Paris despite only joining in the summer.
He is likely to cost over £50 million - and the sale of Lukaku, potentially to Everton, could make that possible.
The club announced they had agreed a deal with his club FC Basel on Friday - but Liverpool have now outdone them with an £18.5 million bid.
Chelsea however are now said to be upping their offer to £20 million to tie down the ‘Egyptian Messi’.
