Fernando Torres sealed his record-breaking move to Chelsea and David Luiz also looked to have completed a mega-money deadline-day switch to Stamford Bridge.
Torres and Luiz both beat the 11pm cut-off to join the Barclays Premier League champions, who splashed out an incredible £75million on the pair.
Striker Torres arrived for a reported £50million from Liverpool, smashing the transfer record between British clubs, while Benfica finally allowed defender Luiz to move on in a £25million-plus deal.
After signing a five-and-a-half-year contract at Stamford Bridge, Spain striker Torres told his new club's official website, www.chelseafc.com: "I am very happy with my transfer to Chelsea and I am looking forward very much to helping my new team-mates this season and for many years to come.
"Having played against Chelsea many times since coming to England, and in some very big games I will never forget, I know there are many great players here and I will work hard to win a place in the team.
"I hope I can score some important goals for the supporters to enjoy this season."
Chelsea chairman Bruce Buck said: "This is a very significant day for Chelsea, capturing one of the best players in the world with his peak years ahead of him.
"We have long admired the talents of a player who is a proven goalscorer in English football and Fernando's arrival is a sign of our continuing high ambitious. I hope every Chelsea fan is as excited as I am with this news."
