Gremio is preparing for the team's return to training on Wednesday after the holiday break, and coach Luís Castro faces significant challenges. After an underwhelming first half of the season, the team has a busy schedule ahead, and the coach, who was booed in the last match at the Arena, needs to provide quick answers. Gremio's next commitment is scheduled for July 23, against Bolívar, away from home, in the Sudamericana playoffs. The search for consistency is one of the main points to be addressed by Luís Castro, who admitted the team's instability after the loss to Corinthians. He highlighted that the lack of consistency and injuries have hindered the team's performance, which has not managed to win more than two consecutive matches in the first half of the season. Additionally, Gremio is the third-worst away team in the Brasileirão, without any victories on the road. Another challenge is defining a playing model, as after 150 days of work, the team still lacks a clear strategy. Luís Castro has tested different formations, but some decisions, such as using three center-backs in crucial matches, have been questioned by fans. The club's financial situation is also a concern, as the sale of key players like Viery and Gabriel Mec could impact the squad. The coach will need to find suitable replacements, possibly utilizing young talents from the youth academy. The uncertainty surrounding midfielder Arthur's future, whose contract ends at the end of the month, is also a critical point that needs to be resolved quickly.
