The MLS club emerged as the top candidate to land Casemiro after revealing he was leaving Manchester United, seeing the Brazilian as a perfect replacement for Sergio Busquets.
Casemiro has enjoyed an exceptional campaign at Old Trafford, combining his ball-winning qualities and playmaking attributes with nine Premier League goals.
The 34-year-old will play his final game for the Red Devils against Brighton & Hove Albion on Sunday, and then, according to Fabrizio Romano, will seal a transfer to Inter Miami.
Lionel Messi's side are confident of completing a move before the World Cup starts on June 11 after Casemiro was called up for Carlo Ancelotti's Brazil squad.
A new challenge therefore beckons for the former Real Madrid star this summer after spending four years at United.
