Gattuso didn't stay with teams for long when appointed as a coach. This could suggest that he might not have the qualities required to be a successful coach. The teams he managed previously seemed disorganized. However, at Marseille, things seem to be going better. Coaching Olympique Marseille is a challenging task, but Gattuso seems determined to become a promising coach there. The upcoming match against Nice is anticipated to be challenging for both teams, and Nice occupy second standing in the league doesn't guarantee an easy victory.
Gattuso's goal in training the team hard is to improve the team's poor mentality, this was also done by Gattuso when he previously coached Valencia. Actually, this cannot be proven yet, not a single club is willing to be patient. So Gattuso's quality has not been fully proven.
Hopefully at Marseille he will get the support he deserves, and it is true that against Nice like this it will be a challenge for Gattuso to prove that he really has the capacity to be a coach. The victory against Nice is also necessary to increase the team's self-confidence to update the standings where currently Marseille itself is in sixth place with twelve points.
