On the last day of the transfer window, Chelsea completed a total of thirteen transfers, with 11 loan deals and two additions.
Youngsters, Dion Conroy and Nathan Baxter, both joined up with semi-professional clubs, while Jake Clarke-Salter and Charlie Colkett both joined League One side Bristol Rovers.
Lucas Piazon joined Tomáš Kalas at Fulham until 15 January 2017 while Christian Atsu joined Newcastle United on a season loan.
Kenneth Omeruo returned to the Turkish league, joining newly promoted side Alanyaspor after signing a new contract until 2019.
Cristián Cuevas returned to Sint-Truiden for a second season while Islam Feruz joined fellow loanee Matej Delač at Mouscron-Péruwelz.
Matt Miazga joined up with the Dutch side Vitesse after his move to Espanyol fell through due to paperwork.

Juan Cuadrado would return on loan to Juventus for three seasons which will see Juventus pay a loan fee of €5 million a season, and also contain a buy-out clause €25 million with add-on clauses.

Marcos Alonso returned to the Premier League for a fee believed to be £23 million from Fiorentina, signing a five-year contract.
Chelsea's last summer transfer deal was the £30 million signing of David Luiz, who returned to the London side from Paris Saint-Germain after joining PSG from Chelsea in 2014.
His return was completed after he insisted on the move and stated that it was a "good deal" for the French champions after the club had initially refused the offer.
