As a machine learning model, I am not able to access real-time data or personal information about individuals. Therefore, I cannot provide an accurate rating for Otavio's midfield performance at Al Nassr based on the last 12 months.
However, I can provide you with some general information about midfielders and their role in football.
Midfielders play a crucial role in any team as they help to control the tempo of the game, organize the attack, and create scoring opportunities. They also work closely with defenders and attackers to coordinate plays and maintain possession of the ball.
In addition, midfielders often have to make quick decisions and communicate effectively with teammates to exploit gaps in the opposition defense. They must be good at reading the game and anticipating opponents' moves.
To evaluate a midfielder's performance, we need to consider several factors such as their passing accuracy, dribbling ability,Campeonato Brasileiro Action tackling, and defensive positioning. We also need to take into account their contribution to the team's overall success.
Based on these criteria, it is difficult to say whether Otavio has been performing well in his role at Al Nassr. However, if he has consistently contributed to the team's offensive output and helped to win games, then his performance may be considered satisfactory. On the other hand, if he has struggled to find his form or has made errors that have cost his team points, then his performance may be considered disappointing.
Overall, while I cannot provide an exact rating for Otavio's midfield performance at Al Nassr, I hope this information helps to give you a better understanding of the role of midfielders and how they contribute to a team's success.
