Inter defender Dodo claims compatriot Neymar has "always been incredible" as the Barcelona forward battles to regain full fitness.
Neymar is expected to miss Barca's La Liga opener against Elche on Sunday after suffering an ankle injury - just a week after the Brazil international recovered from a fractured vertebra that he sustained during his the World Cup quarter-final against Colombia in July.
Despite having suffered two setbacks in as many months, Dodo – who previously played with Neymar in the Brazil Under-17 squad – is confident the 22-year-old will quickly be back to his best.
"We are childhood friends," Dodo told Gazetta dello Sport.
"At 8 years old, we played futsal together, we were neighbours. He's always been incredible.
"Now, after the accident, I know that he will be fine."
Dodo recently completed a €9million move to Inter from Roma after having been deemed surplus to requirements following Ashley Cole's arrive at the Stadio Olimpico.
The defender, though, thanked Rudi Garcia for giving him opportunities in the first team last season and is now fully focused on restoring Inter's place at the top end of Serie A.
"At Roma, evidently they made other choices," he said. "Garcia? If he had not believed in me, I would not have played so much in red and yellow.
"It was fate that sooner or later I would come here [Inter]. Do not talk about the Scudetto, though. Now we just have to prepare for our first game in Serie A.
"Our dream, however, is to bring Inter back to the top."
