Although they are similar in terms of worth and data, whether they are in the same tier or not depends on the individual's views and preferences.
Mbappe currently plays for Paris Saint-Germain and he has been in excellent form this season. He lived up to expectations, scoring 21 goals and providing two assists in 22 appearances. His goalscoring efficiency was also impressive, scoring a goal in just 89.09 minutes. That made him number one in the scorers' charts and helped PSG stay at the top of the table.
Haaland, on the other hand, played for Manchester City and also showed extraordinary quality. The 23-year-old has scored 19 goals and provided five assists in 22 appearances. With a goal efficiency of 98.42 minutes/⚽, he is also the top scorer leader. Manchester City are third in the table and Haaland's performance has been a major boost to the team's attack.
Statistically, both Mbappe and Haaland have excellent scoring ability, and their value and performance are very close. However, when judging whether a player falls into the same bracket, there is also a need to consider their skills, all-round ability, and impact on the team. This is a subjective judgment, so different people may have different opinions.
Overall, both Mbappe and Haaland are young players with the potential to become world-class stars. Whether they are in the same bracket or not, we should expect them to continue to perform well in their future development and competitions.
