Manchester United's upper brass have to be scratching their heads over this one.
In his 27-year tenure at Old Trafford, it is testament to Sir Alex Ferguson's transfer market nous that the only players his critics can hold on to when they question his signings are Eric Djemba Djemba, Kleberson, Juan Sebastian Veron, Bebe and Ralph Milne.
However, allowing Paul Pogba, now 20, to leave United has to rank high in the list of Ferguson's biggest mistakes - especially as he is the sort of player the club would love to possess right now.
Last season, Pogba caught the admiring eyes of many clubs across the continent due to his physical prowess, aerial ability, his penchant for dribbling, vision, the array of passes that he can pick from and his ability to deliver an exceptional through ball.
His form this season has been even better.
From 18 appearances in Serie A, he has returned five assists and five goals (directly affecting the scoreline once every 148 minutes he is on the pitch). He is just as effective in Champions League competition also, providing three assists from 540 minutes.
While he joined Juventus for free from United, he will likely not leave for cheap. Transfermarkt.co.uk have him valued at £30m.
