The Nerazzurri believed they had a deal in place to sign the 22-year-old, but with just Imbula’s signature missing on a four-year deal, Porto produced a better offer at the last-minute.
L’Equipe report that Imbula has chosen the 27-time champions of Portugal and is expected to soon put pen to paper on a five-year contract, with the Dragoes paying a fee of around €25 million.
AC Milan had also been in the hunt for the Marseille youngster after losing out on the signing of his French compatriot Geoffrey Kondogbia to their city rivals.
AC Milan could be a future destination for Imbula with La Gazzetta dello Sport suggesting Doyen Sports chief executive Nelio Lucas, an advisor to Milan shareholder Mr. Bee Taechaubol, may have proposed to Porto a future move to the Rossoneri.
Imbula was a mainstay at the heart of Marseille’s midfield last term, making 37 league starts and scoring twice for Marcelo Bielsa’s men.
