A busy week for Sanchez had seen him depart Inter on Monday when his contract was terminated, before Marseille announced a deal in principle had been agreed on Wednesday (AEST).
Marseille fans were made to wait little longer for formal confirmation of an eye-catching signing.

The former Barcelona, Arsenal and Manchester United man arrives in France looking to recapture his best form, having started only seven matches in Serie A last season – albeit he still scored five goals.
Sanchez had netted seven for Inter the previous season, again often appearing from the bench, as the Nerazzurri won the Scudetto.
Marseille's statement on Wednesday described Sanchez as "a world-class player with a great experience of the very highest level".
