Lionel Messi scored his 50th goal for Inter Miami as they came from behind to beat Porto 2-1 for their first win at the FIFA Club World Cup.
Porto took the lead after just eight minutes when Samu Aghehowa squeezed a penalty under the arm of goalkeeper Oscar Ustari.
Telasco Segovia also scored for Inter while Samu Aghehowa scored for Porto.
Messi's decision to join Inter Miami in July 2023 led to some criticism that he was leaving Europe too soon.
