The 1986–87 Serie A season ended with S.S.C. Napoli doing the "domestic double", winning their first Scudetto and third Coppa Italia, spurred on by their talismanic captain Diego Maradona, who had also just played a key part in World Cup glory for his home country of Argentina.
He began working in 1986 as a commentator on Radio Peter Flowers, and in 1988 he moved to Telelombardia to do the official commentator of the matches of Inter in the transmission Qui studio a voi stadio, commenting live the victory of the 1989 Scudetto won by Giovanni Trapattoni as coach.
In his first year he netted once in 21 appearances, adding another in five UEFA Cup matches; he would be used regularly during his three-year stay, proving himself a threat at set pieces as the capital outfit lifted the Scudetto in his second campaign.
Their arrivals were part of an effort by club president Vittorio Cecchi Gori to make the squad more competitive for the title run as well as to keep club legend Gabriel Batistuta happy, since the famous striker who recently turned 30 started considering his option to leave in search of the Scudetto that eluded him for years.
With Giovanni Trapattoni's Juventus club, Tacconi won 2 scudetti in 1984 and 1986, the European Champion Clubs' Cup in 1985 and the Intercontinental Cup the same year against Argentinos Juniors on penalties.
