Following Antonio Conte's departure just two days into pre-season preparations, Juventus must act quickly to replace the man who brought them three consecutive Serie A titles.
As they look to build on the foundations of the 44-year-old's success and improve their European record, the Turin giants have several options to take over the hotseat at the Juventus Stadium.
The former AC Milan boss is the favourite to take over for the 44-year-old and Goal understands that contact has already been made between Juventus and Allegri's representatives over the possibility of him taking the helm at the club.
Allegri took over Milan after an impressive spell at Cagliari and guided the San Siro club to the Serie A title in his first season and took them beyond the group stages of the Champions League each time before the team's major collapse in 2013-14.
Following his departure from Galatasaray, the former Inter and Manchester City boss has been linked to the vacant national team job but has entered the fray as a contender for the hot seat at the Serie A champions.
The Turkish side beat Juve to second place in their Champions League group last season and while the 49-year-old had an excellent record of winning the Scudetto three times at Inter, his European record is a black mark on his reputation and could go against him when Juve consider their options.
The former Udinese and Roma boss is back in the market once again after he left Zenit St Petersburg with two Russian league titles, a Russian Cup and Russian Super Cup.
The 55-year-old, who won back-to-back Coppa Italias with Roma, has also been linked to replace Cesare Prandelli at the national team but could also be one for the Bianconeri board to consider as they look to replace Conte.
The 45-year-old is reportedly considering leaving Sampdoria after several figures within the club have resigned following Massimo Ferrero's takeover earlier this year.
After good spells at Catania and Fiorentina followed by his bright season with Sampdoria, the former Serbia coach will be looking for his chance at a higher club and will be seen as an outsider for the Bianconeri job.
