Parma 1-0 Juventus: Pellegrino dents visitors' top-four hopes
Juventus suffered their first defeat under Igor Tudor, following a toothless display against relegation-threatened Parma on Wednesday.
Juventus missed the chance to return to fourth place in Serie A following a 1-0 defeat by lowly Parma.
Mateo Pellegrino scored the only goal at Stadio Ennio Tardini, where the hosts eased their relegation fears by moving six points clear of the bottom three.
A dull first half burst into life in stoppage time, when Pellegrino met Emanuele Valeri's looping cross to bury a header beyond Michele Di Gregorio.
Chances were also limited after the break, with both struggling to create many genuine opportunities in attack.
Juve pushed for an equaliser towards the end and Francisco Conceicao drilled narrowly wide in stoppage time, as the Bianconeri suffered their first defeat under Igor Tudor.
Data Debrief: Resurgent Parma pull clear of danger
Parma continued their resurgence under Cristian Chivu, who took charge in February. Since he took over, the Gialloblu have registered 11 points in eight Serie A games; the second-most among bottom-half sides after Como (14).
Beating Juventus for the first time in Serie A for 10 years, Parma have also gone unbeaten in six successive top-flight games for the first time since 2014.
Pellegrino was the hero. Aged 23 years and 183 days, he is the youngest player to be involved in at least one goal in three consecutive home appearances in Serie A for Parma since Jonathan Biabiany (23 years and 143 days in September 2011).
It came via a cross from Valeri (five), who is one of four Italian defenders with at least five assists in Serie A this season, along with Raoul Bellanova (eight), Federico Dimarco (seven) and Tommaso Augello (six).
