Silva has signed a deal with the club until the end of the 2025-2026 season after terminating his contract with Fluminense six months early. 

He was linked with a return to Chelsea, with a move to European football believed to have materialised because of Silva's intention to play at the FIFA World Cup in 2026.

The Brazilian returns to the club whose colours he represented in 2004-2005, albeit in the reserve team, making 14 appearances for Porto B before transferring to Dynamo Moscow.

"I'm here to announce my return to the Dragons and to say how happy and flattered I am by this opportunity," Silva said.

"I'm super motivated. I hope I can help in the best way possible.

"I would like to thank our president, Andre Villas-Boas, for the opportunity and our coach, Francesco Farioli, as well, and say how eager I am to wear these colours again.

"I count on your support, and I hope to see you at the Dragao."

Silva arrives at Porto with 31 trophies to his name, one of which came at Estadio do Dragao in 2021, when he lifted the UEFA Champions League with Chelsea.

The defender spent eight successful years with Paris Saint-Germain between 2012 and 2020, before making 155 appearances in all competitions for the Blues.

He then returned to his homeland for a second stint with Fluminense, leading them out at the FIFA Club World Cup over the summer.

Silva's first appearance for his new team could come this Tuesday (AEDT), with Porto taking on Alverca in the league as it looks to increase its five-point lead at the summit.
