The Brazilian already confirmed his departure from United in January, with his contract expiring at the end of June.
Casemiro has been indispensable to Man United's successful campaign, spearheaded by Michael Carrick's return, as they confirmed their return to Champions League football.
The 34-year-old has chipped in with several crucial goals, scoring nine times in the Premier League, his most prolific return since joining the club in 2022.
It's going to be emotional for Casemiro and everyone associated with United once he says goodbye to Old Trafford, and Inter Miami appears to be his "most likely destination".
"MLS for sure and I’m told that terms have almost been agreed with Inter Miami," transfer guru Ben Jacobs said on GiveMeSport's Market Madness podcast.
"It’s not done yet, but La Galaxy, the other club in MLS, feel like Inter Miami is now the most likely destination even though they’ve not given up, so it’s between those two clubs.”
MLS is typically a retirement home for some of the world's greatest footballers, and he is surely excited about linking up with Lionel Messi at Inter Miami after playing against him in several El Clasico's.
