Fulham have completed the signings of Willian on a free transfer and Layvin Kurzawa on a season-long loan.
The arrivals take the number of acquisitions made by the Premier League club this summer to nine.
Ex-Chelsea and Arsenal midfielder Willian, 34, had been playing with Corinthians.
However, the 34-year-old had his contract cancelled with the Brazilian club after claiming he and his family received death threats on social media.
Willian won five trophies, including two Premier League titles, during his seven-year spell at Chelsea before joining Arsenal on a three-year deal in 2020.
His deal with the Gunners was terminated after a year because he did not make an impact and he moved back to his first club Corinthians in his homeland.
Willian told Fulham’s club website: “I’m happy to be here, I’m happy to be back in the Premier League.
“Fulham is a special club, a club that wants to improve, that wants to fight for something bigger, so I’m here to help, and I can’t wait to get started.”
Left-back Kurzawa, 29, has made 153 appearances for French champions Paris St-Germain since arriving from Monaco in 2015 but is yet to feature in Ligue 1 this term.
“I feel very, very happy to be here. It’s a family here, everyone is very cool,” he told the club website.
“I’ve watched every Fulham game this season, and I can’t wait to play with this team.”
Meanwhile, back-up goalkeeper Paulo Gazzaniga departed Fulham on deadline day, joining Spanish club Girona on a season-long loan.
