Alvaro Pereira completed his move from Porto to Inter Milan and said he found the thought of playing for the club "simply amazing".
Pereira, 26, arrived in Milan on Friday, but it has taken time for the Lega Serie A to register the Uruguayan full-back's transfer.
The move is believed to have cost Inter around €13.5 million, and Perieira told the club's official website: "Inter is a dream - you just cannot imagine how much this club is loved and supported abroad.
"Inter is every player's dream, and even more so in South America. I'm happy, and the thought of playing for Inter is simply amazing." "
Pereira enjoyed a hugely successful career in Portugal - particularly under Andre Villas-Boas - winning two League titles, two Portuguese Cups, four Portuguese Super Cups and the Europa League.
He said he hoped to continue in the same vein at the San Siro, adding: "Let's hope we can win a lot of trophies so we can make the Inter fans happy.
"I'll team up with Gargano and Guarin - fortunately, I have these friends here who will help me settle in with the rest of the squad quickly.
"Where do I prefer to play? What's important now is being at Inter and meeting my team-mates. What have Guarin and Gargano told me? That Inter is a fantastic club."
