The Italian giants have added another new face to their squad as they try to compete for the Serie A title this season.
Borja Valero, Facundo Colidio, Milan Skriniar and Matias Vecino have already joined the club earlier this summer and Dalbert has arrived just weeks before their clash against Fiorentina at home.
Reports claim Inter have paid 20 million euros to bring him to the San Siro and they have confirmed the news in a statement on their official website.
It read: "Dalbert Henrique Chagas Estevao is now an Inter player, with the Brazilian full-back signing a contract until 30th June 2022.
"Last summer, Nice took a chance on Dalbert and it turned out to be a great decision. The Brazilian established himself as one of the most interesting left-backs in Ligue 1, as he made 33 league appearances; one in the French Cup and four in the Europa League.
"Under Lucien Favre, Dalbert showed great physical and technical ability as he got up and down the flank and he came up with four assists last season. Furthermore, he was the Nice player with the most crosses  and the most dribble attempts .
"Now, he’s a Nerazzurri player. Welcome to Milan, Dalbert and good luck for our new adventure together!"
