But as speculation about Inter Miami's new possible coach mounts, the official announcement remains under wraps, leaving fans and analysts eagerly awaiting confirmation.

Lionel Messi is on the cusp of reuniting with former Argentina national teammate Javier Mascherano with Inter Miami, this time as player and coach, a person with knowledge of the negotiations told The Associated Press.

The concern at the moment is who his coach will be. Multiple outlets reported on Friday that Inter Miami have agreed on a deal with former Barcelona player and current Argentina youth manager Javier Mascherano. While it seems a natural fit, as Martino showed, success in MLS is not guaranteed.
