Juventus have appointed former AC Milan manager Massimiliano Allegri as their new boss. Allegri, 46, was sacked by Milan in January and replaces Antonio Conte, who left the Italian champions on Tuesday. "It is an honour for me," said Allegri. "I'm very happy and I know what a big job coaching Juventus is." Juventus director Giuseppe Marotta said: "Juve's aim has always been to keep winning, a real must given the club's prestige and past success." Allegri, who has also coached Cagliari, won the Serie A title with Milan in his first season in charge in 2010-11.
