And Porto made sure to announce the legendary defender’s arrival in style, employing the services of transfer guru Fabrizio Romano in a social media post.View Tweet: https://twitter.com/FabrizioRomano?ref_src=twsrc%5EtfwSilva ‘flattered’ to join PortoIn a video shared on the club’s X account, Romano said: “Hello Portistas! Breaking news I can reveal for you, a special Christmas gift. “The legend, the Brazilian defender Thiago Silva has signed with FC Porto.

God bless.”Thiago Silva’s career achievementsThe news of Silva’s arrival at Porto comes just days after the centre-back left Fluminense following the termination of his contract.He joined the Brazilian giants in the summer of 2024, after departing Chelsea, but opted to depart the club six months before his deal at the club expired.In the days that followed, Silva was tipped to make a spectacular move back to the Premier League, with legendary former captain John Terry calling for the club to resign him.Terry insisted the established star would bring valuable experience to the Blues’ young squad.GettySilva won the Club World Cup with Chelsea in 2021[/caption]But Porto will now be the main beneficiaries of this, as they look to clinch their first league title since 2022.They are currently top of the Portuguese Primeira Liga — five points clear of second-place Sporting CP, having dropped just two points in 14 league games this term.It’s fair to say Silva knows a thing or two about winning trophies, having won 31 in total across his 986-game professional career.This includes seven Ligue 1 titles with PSG alone, as well as the 2020/21 Champions League with Chelsea.Silva spent four years at Stamford Bridge, between 2020 and 2024, where he made 155 appearances and scored nine goals, establishing himself as a fan favourite in the process.In just under a year-and-a-half at Fluminense, the defender scored five goals across 66 outings.
