Tuttosport says Juan Cuadrado, Paulo Dybala and Gonzalo Higuain are all part of the same friendship group, nicknamed the 'Panitas', and have remained in regular contact with Pogba since his move to Old Trafford in 2016.
The trio could play a crucial role in sealing Pogba's return to Juventus.
The 26-year-old became an honorary member of the club's South American troop after opting to leave United under the stewardship of Sir Alex Ferguson, with the group often seen producing an abundance of social media material together.
The bond between the star players is thought to have continued over WhatsApp, and they have also visited each other on multiple occasions - with Pogba supposedly a regular visitor to Turin.
The nickname 'Panita' was reportedly introduced by Cuadrado, with the phrase indicating a person always prepared to lend a hand to friends, but also someone with a mischievous personality, reports the Daily Mail.
