Osvaldo Bagnoli's boys were embarrassed by Gennaro Ruotolo in the 52nd minute and lie sixth in an Italian League headed by Parma.
A Swede and a Sardininan inspired the European Cup-Winners' Cup holders to sink Atalanta. Tomas Brolin, with a fine chip, and Gianfranco Zola, once nicknamed 'Merendina' ('little snack') because of his taste for junk food, struck in the second half to maintain Parma's presence at the high table.
Zola and Co are closely pursued by Milan and Sampdoria, who both came from behind to secure 2-1 victories. The champions, trailing to Zola's old club Napoli, stay second thanks to Christian Panucci, a rapidly rising full-back talent who netted with a curling shot, and Demetrio Albertini, the matchwinner with an 89th-minute, 30-yard free-kick.
Sampdoria slipped behind at Foggia when Bryan Roy, the Dutch winger, put the hosts ahead but were saved by the two men with the most contrasting haircuts in Italian - if not world - football: Ruud Gullit and Attilio Lombardo.
The old lady of Juventus nearly had a coronary at home as Cagliari threatened to win at the Stadio Delle Alpi. Juve, who rarely fail in Turin, were within six minutes of defeat when Germany's rugged defender, Jurgen Kohler, headed an equaliser to cancel out Luis Oliveira's solo opener.
Two Marseille maestros offloaded to save the debt-ridden Mediterraneans made goalscoring home debuts. After hitting Reggiana's first in a 2-0 win over Cremonese, Paulo Futre sustained a serious knee injury and will be out for two months.
His former team-mate in France, Alen Boksic, scored against Torino but Lazio still slumped to their first defeat in Rome for nine months. Andrea Silenzi's penalty brought the teams level before the Law of the Returning Reject came into force, Angelo Gregucci scoring the winner against his old club.Reuse content
