Inter Miami head coach Gerardo "Tata" Martino expressed cautious optimism at Lionel Messi's return to the pitch ahead of the game against D.C. United on Saturday, before insisting no final decision will be made until training concludes. Messi failed to travel with Miami for the midweek game against Orlando City at Inter&co Stadium, after a clash with CF Montréal defender George Campbell last week left him in pain.
