Juventus have dealt Manchester United a huge blow in their chase for 29-year-old Leonardo Bonucci, as they have insisted that the Italian is not for sale, as per Tuttosport.
The report states that Juve view the defender as one of the key components of their team, and that they want to hang onto him in order to challenge for the Champions League next campaign.
United were understood to be exploring the possibility of adding Bonucci to their ranks, but the response from the Serie A champions has been a resoundingly negative one.
Mourinho is keen on strengthening his defence, despite the signing of Eric Bailly from Villarreal earlier in the window, and had identified Bonucci as the ideal man to lead his back-line, as per the MEN.
However, with the seemingly imminent announcement of the Paul Pogba deal, chances were very slim that United could also take Bonucci away from Juventus.
