CHELSEA fans could be set for an emotional final game of the season with some key players bidding farewell.
Antonio Rudiger has already confirmed his exit ahead of a free transfer to Real Madrid next season.
And club captain Cesar Azpilicueta could also join Rudiger in Spain as talks with Barcelona progress.
Blues boss Thomas Tuchel admitted Azpilicueta’s future remains up in the air and will leave the Spaniard to decide for himself.
Rudiger started in Chelsea’s 1-1 draw with Leicester and is set to keep his place against Watford in a farewell match.
Azpilicueta could also come in to play in the back three or at wingback for potentially the last time as a Chelsea player.
It leaves Trevoh Chalobah contesting for a spot in the back three with Thiago Silva likely to start.
At left-wingback it could also be Marcos Alonso’s last game for the club as the defender pushes for a move to Barcelona.
Andreas Christensen is believed to have already agreed terms for a free transfer and could be joined by Alonso.
On the opposite flank, Reece James may keep his place but Azpilicueta is the logical alternative.
In midfield, Mateo Kovacic was left out against Leicester while N’Golo Kante also came off.
It leaves Jorginho likely to keep his place in midfield, possibly partnered with Ruben Loftus-Cheek.
Saul Niguez is fit and offers depth as his loan move comes to a close with no signs a deal will be made permanent.
Going forward, Mason Mount was benched last night but is fit to return against Watford.
And he could fill in either on the wing or in a No10 role behind a strike partnership.
If Tuchel opts for a 3-4-1-2, Romelu Lukaku could partner Kai Havertz up front.
But if he selects a front three, the pair will likely be in competition to play through the middle.
Christian Pulisic and Hakim Ziyech could keep their places out wide if that is the case but Mount is also an alternate.
Timo Werner is still injured and will watch the last game of the season from the bench.
