Old memories aside, Zeman fuelled angered Juve lately as he said that, in his opinion, suspended coaches should not be allowed to train their team.The reference was obviously about Juve’s Antonio Conte, who this season is sidelined - only from games, according to sports rules - for failing to report an attempted match-fixing case while he was at Siena in 2011.Conte, who was among the many Juve players questioned in the trial, will be in the stands at the Juventus Stadium, while his assistant Massimo Carrera, also a former Bianconero, steers the players on the pitch.Mid-week action saw Juve slow down after four straight wins and draw 0-0 at Fiorentina, allowing Napoli to draw level at the top on 13 points as Edinson Cavani’s hat-trick downed Lazio 3-0.“(On Tuesday) it was a difficult game,” international defender Giorgio Chiellini tweeted, “but in the end we managed to retain our unbeaten record (of 44 games).”
