A second-half equaliser by Marco Borriello earned struggling Genoa a 1-1 draw at Serie A leaders Juventus on Saturday, denting the champions' hopes of a second successive title.
Former Juve forward Borriello struck in the 68th minute to leave Antonio Conte's side on 49 points at the top, six clear of Napoli and Lazio who earlier suffered a shock 1-0 home defeat by Chievo Verona.
Genoa, playing for the first time under new manager Davide Ballardini, moved up to 18 points but remained third bottom as Chievo climbed to 11th place on 28 points.
The Juve match was marred by controversy over two penalties not given to the champions in the second half and Juventus striker Mirko Vucinic went unpunished for what appeared to be a clear handball in the area.
Luca Antonelli looked to have pulled Vucinic's shirt as the forward stretched for Emanuele Giaccherini's 80th-minute cross, while Andreas Granqvist sparked furious protests from Juventus when he kicked the ball on to his hand in stoppage time but referee Marco Guida failed to award a spot-kick.
The protests from the Juventus staff carried on in the tunnel, with Sky Sport Italia reporting that Conte, Leonardo Bonucci and injured Giorgio Chiellini harangued Guida.
