Allegri has led Juve to back-to-back Serie A and Coppa Italia Doubles in his two years in charge while he is on course for the same this season, with his side also on the brink of a place in the Champions League semifinals after beating Barcelona 3-0 in their quarterfinal first leg on Tuesday.

Allegri has been linked with a move to the Premier League this summer, with Arsenal having been touted as a destination, but Marotta feels he will stick around to achieve more success at the Juventus Stadium.

"I think a cycle for a coach lasts three years, even if Allegri's gone way beyond that," Marotta told Mediaset. "I don't think his cycle has ended. He's shown over time that he has the quality that we have been looking for and he has the ideal profile, and I think we can have much satisfaction together.

"The important thing is winning, but of course you need to entertain when you win too and I think Juve are playing beautiful football and this is what we are after. This game [against Barca] is just the first half and we know our opponents' strength, but we're aware of our own strength too."

Massimiliano Allegri has been linked with a Juventus exit.

Juve's dominant display against Barca saw Paulo Dybala outshine Lionel Messi, scoring Juve's first two goals, and Giorgio Chiellini netting his first in the Champions League since 2009. 

"It was a great night and we're happy. We've beaten one of the best teams in Europe, the strongest attack in the game and if somebody had offered us this yesterday, we could not have asked for more," Chiellini told Mediaset.

"It looks easy from the outside, but PSG [Paris Saint-Germain] would never have thought they would get knocked out [by Barca in the quarterfinals]. We know their strengths and weaknesses and we know they are a fantastic side who rise above themselves in their recoveries. We pressed them as far up the field as we could today and the few chances we did concede to them were saved by the 'Saint' [goalkeeper Gianluigi Buffon] that we have at the back." 

Chiellini also came up against Luis Suarez, who bit him during Italy's World Cup defeat to Uruguay in 2014. After an unfortunate clash which saw Suarez run into Chiellini and fall to the ground on Tuesday, the Juve defender lifted him back to his feet with a smile and an embrace.

"Suarez is a great forward and nobody talks about 'that' Suarez anymore," Chiellini said. "Everything's fine between us now."

Chiellini graduated with a degree in business administration last week, although he says he is not planning to put that knowledge into practice anytime soon.

"It was important and I'm enjoying it with my family, but my job is to play football and have great nights like these," he said. "Football is my life and there's going to be a very important game in eight days. Let's say now I've got a first degree with distinction -- plus three."
