Actually, in this case, the increase or decrease in player performance also depends on how the coach gives trust and freedom to them so that this depends on the attitude of the coach whether his presence will make the player become as expected or decrease in terms of performance.
Napoli players who have decreased now also have a share of Rudi who cannot bring Napoli's performance to the best as before in the era of Spalletti even though this player must also be regretted due to the decline in quality and performance but still the one in control is the coach and Rudi cannot be separated from it.
Rudi Garcia has never been a successful coach in any top-flight club. I don't know why the club decided to give him the job instead of looking for a coach who has past results. His match strategies are strange and his decision to substitute Osimhen and Khvicha Kvaratskhelia during the match against Bologna when the common decision of every coach would have been to push on more attackers is an example of his poor tactical skill. The draw with Union Berlin, a club that is struggling is unacceptable for a club like Napoli. Union Berlin I currently in 16th position in the Bundesliga and shouldn't have been a problem for Napoli. Rudi Garcia needs to wake up and maximize the quality of players at his disposal.
In that match Roma will play away, and in 5 away matches they can only got one winning, and that too against a weaker team. The performance of Jose Mourinho squad was not very impressive when playing away, it was different when playing at home because in their last match Roma were able to make a surprise with their epic comeback. On the other side, Lazio is also not an easy team to beat, and yeah they also have good motivation after beat Feyenoord in Champion league, so it seems like there is a possibility that Lazio can secure full points against Roma.
Roma also had a good match against Lecce when they came back from a goal down to win the game. Paulo Dybala and Romelu Lukaku are in top form so I expect Roma to at least get a draw from the game. But Jose Mourinho be focusing on the Europa League match against Slavia Praha in Fortuna Arena, Prague, Czech Republic. Roma is currently topping Group G with nine points after winning all their games.
