Martinelli, a 24-year-old midfielder, has been a key player for Fluminense since the team's Libertadores title win. He has been a regular starter and one of the team's captains. Ancelotti had previously observed Martinelli in Fluminense's games before the 2026 World Cup, but was unable to call him up due to the presence of established players like Casemiro and Fabinho.

Martinelli has been a standout player for Fluminense, with over 100 appearances for the club. He has also been the subject of interest from other teams, but Fluminense has rejected all transfer offers. The club considers Martinelli to be one of their most valuable players and would only consider selling him if they receive a highly attractive offer.

Martinelli will now join the Brazilian national team for their upcoming friendly matches against Australia and India. This is a significant opportunity for the young midfielder to gain experience and potentially earn a spot in the team for the 2030 World Cup.
