It was a day of huge changes in Serie A, Italy’s top-flight soccer league.

On Friday, Juventus re-hired former manager Massimiliano Allegri just two hours after sacking Andrea Pirlo.

With a statement on their official website, the Turin-based club reinstated Allegri just two years after his departure.

“Allegri finds a bench that he knows very well, a club that he loves and that loves him back, as today a new journey begins together, towards new goals.

“We are ready to build our future together; with his enormous professionalism, his moral strength, with the brilliant ideas of a coach capable of shuffling the cards, both on and off the pitch,” reads a statement on Juventus’ website.

According to several media reports in Italy, Allegri's new four-year deal at the Bianconeri will see him pocket $8,5 million annually, making him the highest-paid manager in the league.

The 53-year-old returns for his second spell in Turin after winning five consecutive titles, including four doubles, as well as guiding the side to two Champions League finals between 2014 and 2019.

The former AC Milan and Cagliari boss reunites with his former club burdened with huge expectations, as Juventus president Andrea Agnelli hopes the manager can add some more silverware to the 11 trophies conquered in his first stint at the club.

Allegri seems to be the best man for the job as he has a proven record of success at the helm of the Old Lady.

Allegri coached Juventus in Italy’s top-flight soccer league for a total of 190 matches, securing 142 wins, 28 draws, and 20 defeats, with a whopping total of 380 goals scored and only 125 conceded.

Additionally, according to Opta data, the Italian tactician owns the highest winning percentage for a Juventus manager in Serie A, managing to secure the 3 points in 75% of his league fixtures.

Allegri was appointed just two hours after Juventus announced the departure of Andrea Pirlo.

With a statement on Juventus’ website, earlier today the club thanked Pirlo for the “special experience together,” wishing him the best of luck.

“For all this, for the courage, the dedication, the passion with which he demonstrated every day, our heartfelt thanks go out to Andrea, as well as our good luck for the future that will surely be a wonderful one,” the statement read.

Pirlo's first and only season in charge of Juventus was hugely underwhelming.

The Maestro has overseen one of their worst campaigns in the last ten years, where Juventus ended fourth in Serie A, losing the title for the first time since 2012 and finishing 13 points behind champions FC Inter.

Additionally, Juventus quit the Champions League quite early, knocked out by FC Porto at the Round of 16 stages.

Winning the Coppa Italia against Atalanta and the Super Cup against SSC Napoli was just not enough for the 41-years-old, even though it was Pirlo’s first appointment as a manager.

Despite the disappointing campaign, Pirlo admitted the past season has convinced him he wants to continue his coaching career.

"This adventure, despite an unexpected ending, made it even clearer what I would like my future to be, which I hope is as complete and full of satisfaction as what I experienced as a footballer," said Pirlo in his farewell message to Juventus’ tifosi.

According to Italian transfer market pundit Gianluca di Marzio, Pirlo might replace Roberto De Zerbi on Sassuolo’s bench after his departure to the Ukrainian side Shakhtar Donetsk.

While Juventus fans were delighted to hear the news of Allegri’s return, it remains to be seen whether Allegri would be able to maintain his impressive numbers throughout his new beginning.

It will be an interesting summer ahead for the six-time Scudetto winner.  

The transfer market windows will start on July 1 and the manager will have to do without chief football officer Fabio Paratici, who stepped down last week after eleven years in service.

The club board hopes that Paratici’s deputy Federico Cherubini will be able to replace him successfully, but many issues lie ahead.

First and foremost, the new management will have to sort out the future of the talisman Cristiano Ronaldo.

The 34-years-old Portuguese superstar - who netted 36 goals across all competitions in 2020/21 - has been linked in recent weeks with a sensational return to Manchester United, due to the disappointing result of the last campaign.

Will Allegri manage to do the trick again?
