Chelsea are going into the upcoming summer transfer window in unusual circumstances, where they are already aware of who their biggest addition may be.
The Blues have already completed a deal to sign Estevao Willian, set to go through at the end of the domestic season.
Chelsea believe they have hit the jackpot with the signing of Estevao, however will be handed one final chance to take a look at him up close before his move is official.

Estevao says he will celebrate if he scores against Chelsea at Club World Cup
Palmeiras have joined Chelsea in the Club World Cup, with the youngster already knowing he will get the chance to play against Lionel Messi and Inter Miami.
There is the chance that their path could cross with Chelsea too, meaning he would be coming up against the likes of Cole Palmer and Moises Caicedo just days before he will be training alongside them.
The youngster was asked by journalist Fred Bruno whether he would celebrate a goal scored against the Blues, and his answer was pretty clear.
He said: “Of course I will, as long as I don’t wear Chelsea shirt I’m fine!”
Chelsea will be coming up against Flamengo, ES Tunis and Club Leon in the group stages of the competition in the United States.
However, Sky Sports have reported how the summer tournament could be a real burden for Chelsea, with the Premier League not altering their schedule for them.

Chelsea’s plan for Estevao
Given the fact that the winger is still so young, it could be forgiven to believe that a loan away is what’s needed for the Brazil international.
However, Chelsea plan for Estevao to be in Enzo Maresca’s squad from next season, competing for first team minutes.
The majority of his appearances come on the right of attack for his current club, and this could pose an issue for Noni Madueke and Pedro Neto.
Neither player has been able to establish themself as a guaranteed starter at Stamford Bridge this season, and could find their minutes dwindle if Estevao starts off how many expect him to in the Premier League.
