Gerardo Martino refused to comment on suggestions that Lionel Messi was saving himself for the Copa America, following Inter Miami's 3-1 defeat by Atlanta United.

Despite his 11th goal of the season - and first in three games - Messi was unable to prevent a first loss in 11 MLS matches for the Eastern Conference leaders at Chase Stadium.

Saba Lobjanidze scored in each half to put 12th-place Atlanta in control and, though Messi halved the deficit, Jamal Thiare struck in the 73rd minute to snap the visitors' nine-game winless streak.

Messi, who was back in the starting line-up after missing Miami's 2-1 victory over Vancouver Whitecaps last time out, will soon link up with Argentina ahead of their Copa America title defence, which starts in a couple of weeks' time.

Martino was asked whether he thought the eight-time Ballon d'Or winner's focus was distracted by the forthcoming tournament in the United States, where the reigning world champions will seek their third silverware in four years.

"No, I will not speculate if Messi is saving himself for Copa America because [that question has] no validity," the head coach said.

On Miami's performance, he continued: "The first feeling is that we were missing one more gear compared to Atlanta, and that was evident in the first half and during the second half. 

"It was a night where the team regressed compared to other games. I think we were very well outmatched, and they beat us well.

"The conditions were favourable, much more for us than them. But their position on the table is deceiving, and they showed that."
