Massimiliano Allegri warns stars against Juventus exit amid Leonardo Bonucci and Paul Pogba links

Juventus boss Massimiliano Allegri has urged any players currently considering leaving the reigning Serie A champions to think "very carefully" after persistent rumours suggesting that both Leonardo Bonucci and Paul Pogba could be set for respective summer transfers to the Premier League.

After impressing alongside experienced club teammates Gianluigi Buffon, Giorgio Chiellini and Andrea Barzagli as part of a miserly and typically cynical Italian defence at Euro 2016, uncompromising centre-back Bonucci has been strongly linked with both Pep Guardiola's Manchester City and a potential reunion with former Juve and Azzurri head coach Antonio Conte at Chelsea.

Ludicrously gifted star midfielder Pogba, meanwhile, was ultimately unable to follow in the footsteps of iconic compatriots Michel Platini and Zinedine Zidane and guide beaten finalists France to major tournament glory on home soil.

That failure has done nothing to dampen rumours over a prospective return to Manchester United, with recent reports from Sky Sports even claiming that executive vice-chairman Ed Woodward has entered negotiations over a world-record £100m ($131.9m) deal for a player that departed Old Trafford on a free transfer in 2012 amid frustrations over a lack of first-team opportunities under Sir Alex Ferguson.

Allegri appears unconcerned by such speculation, however, and clearly believes Juventus are prestigious enough to retain their best players. He told Gazzetta dello Sport: "I am calm about the English rumours. Anyone who has the opportunity to leave Juventus has to consider things very carefully, because right now Juve are among the top four European clubs.

"This is not a selling club that just lets its players go. Pogba belongs to Juve and at the end of the day he too will want to win another Scudetto and hopefully the Champions League. We have grown in terms of appeal and awareness of our own capabilities. So far our market this summer has been eight out of 10, bringing in players of international pedigree like Medhi Benatia, Dani Alves and Miralem Pjanic."

The arrival of Benatia from Bayern Munich on a season-long loan deal, leaving Allegri with a veritable glut of central defensive options that also includes young Daniele Rugani, has only served to further fuel doubts over Bonucci's future in Turin. The Manchester Evening News now claims that powerful agent Mino Raiola has not set an official deadline for United to complete their ambitious deal for Pogba.

"The France internationals will return on August 7," Allegri told reporters of his return from international duty. "Both [Patrice] Evra and Pogba? They are both Juventus players and I hope they will stay. I am counting on Pogba."
