86/87 was third best as well, behind Internazionale and Como and, joint third alongside Milan and Sampdoria. Then maybe, goal involvement should indeed be looked at instead of direct assists. Since it feels a bit anomalous that a player with Maradona's tendencies for constantly wanting to be involved, would have so little goal involvement in a season wherein he featured in 29/30 games in the league and his team ended up doing so well. Napoli has invested quite decently to build the current team as well. Deducting earnings through player sales, they are ahead of Juventus in terms of expenditure 43 vs 40 million pounds, since 2013/14 i.e. when Higuain was bought. Higuain's fee is a substantial part of that, but even then, they have done their bit to shore up the team with spending post earnings of more than 150 million pounds since their rise from relegation in 06/07. Inter as an example during the same time frame have spent 70 million pounds, post earnings, which might be considered to be an important factor in their recent standings in the league. (Source: Transfermarkt) In any case, regarding the nature of Napoli's win in 86/87, rather than thinking of it as miraculous I have always felt it was pioneering. And indeed, whatever else might be said, at the end of the day the league back then was quite a bit more rough than it is today, which is a point of major importance for attackers wanting to perform, one that is brushed aside a bit too easily these days in favour of other stats. Lastly, while in 86/87 it is visible that Maradona's statistical impact was more against lower ranked teams, its not like his team was doing so well against the other top teams without his impact i.e. Juventus, Inter and Verona (2 wins, 2 draws, 2 losses). So the statistical impact in vanquishing the smaller teams did indeed come in handy in winning the league at the end (considering that it was against against these same lower ranked teams that the other teams failed to perform equally well, apart from the case of Juventus who are even worse than Napoli against top teams). Most importantly though, in case of Maradona more so than Higuain, the lack of any statistical impact does not necessarily translate into a bad game, considering the difference in roles.
