Napoli are about to sack Rudi Garcia and the statistics show that in 75 per cent of cases, a change of coach in Serie A has boosted the average results.
Some clubs are reticent to dismiss their tacticians mid-season and President Aurelio De Laurentiis had already resisted the temptation last month.
He now seems ready to wield the axe over Garcia, with Igor Tudor and then Walter Mazzarri emerging as candidates to take over.
According to a study from Calcio e Finanza, a change really is most of the time good for teams at club level.
Since the start of the 2018-19 Serie A season, it was found that 39 out of 52 new coaches had better results than their predecessors when changed mid-term.
That is an impressive 75 per cent success rate.
In the current campaign, there have already been boosts for three clubs that changed coach.
Udinese have gone from an average of 0.67 points per game under Andrea Sottil to 1.67 with Gabriele Cioffi.
Pippo Inzaghi boosted Salernitana’s average from 0.38 points under Paulo Sousa to 0.5 points, so a slight improvement.
The biggest shift was seen with Empoli, who had lost all their matches under Paolo Zanetti, only to climb to 1.25 points per game under Aurelio Andreazzoli.
Over the last six seasons, Serie A saw an average improvement of 0.29 points per game in teams who changed their coach.
The man who made the biggest impression was Tudor, who at Verona in 2021-22 went from 0 under Eusebio Di Francesco to 1.51 points per game for the Croatian.
