Inter Milan are reportedly about to sell two players to help fund their move for Manchester United striker Romelu Lukaku.
The Belgium international is new Inter boss Antonio Conte's top summer transfer target.
Lukaku is valued at £75m by United, however, and the Italian side do not currently have the money to complete a move.
Mario, who has previously spent time on loan in the Premier League with West Ham United, is said to be heading to Monaco in a £22m deal, while £18m-rated Dalbert will either join Monaco or Ligue 1 rivals Lyon.
Inter are rumoured to have asked United about the possibility of an initial loan move for Lukaku, but the Red Devils want to offload the 26-year-old permanently before the new season begins.
