Look away now, Manchester United fans. Or just Sir Alex Ferguson.
Paul Pogba is absolutely ripping it up in Serie 'A' at the moment, and anyone who saw his performance for Juventus against Chievo yesterday will know why he's one of the most wanted players in Europe.
Indeed, the Red Devils are thought to be one of the clubs interested in bringing the Frenchman back to England. £75million is the mooted figure, according to the Daily Mirror.
It's easy to forget that Pogba was on the Manchester United books as a teenager, joining in somewhat controversial circumstances from Le Havre back in 2009. His talent was evident in the Academy ranks - a point proved by his goal against Derby County.
The strike came at a time when the Frenchman was trying to make a case for first team recognition in March 2011. His touch, control and finishing ability are all evident in the video below...

This hidden YouTube gem is likely to frustrate Manchester United fans even more. There are still questions about why the teenager was allowed to leave, and subsequently become such a force in the Italian top flight.
Fergie's biggest mistake?
Ferguson made some great signings in his time at Old Trafford, as well as the odd transfer mistake (Bebe, anyone). But Pogba ranks right up there as both his best and worst piece of business with the Red Devils.
Fans will point to Ronaldo as Fergie's best piece of business, but consider that Pogba cost a nominal fee following a confidential agreement between the two parties involved. He is now one of the world's best players at 21.
Where would Manchester United be in the table with the mercurial Frenchman in their team this season? Where would they have finished last season under David Moyes if Pogba was pulling the strings in midfield - a problem position for the club?
And what was Pogba doing last season? Scoring goals like this...
So yes, it's fair to say the decision to let him leave the club was a bad one. Ferguson simply couldn't get him into the Manchester United team, with a sporadic League Cup appearance not enough to satisfy the midfielder.
There were also question marks over his attitude whilst at Old Trafford, but the decision to play Rafael and Ji-Sung Park in central midfield on New Year's Eve in 2011 would be enough to tip anyone over the edge. Pogba watched from the bench during that defeat.
Nobody is suggesting Pogba's attitude isn't all that now, and with over a decade of football ahead of him, United fans are right to wonder what the hell actually happened.
