Manchester United released Paul Pogba on a free back in 2012 after refusing to give in to the French midfielder's wage demands.
Fast forward three years and as Pogba celebrates his third consecutive Serie A title alongside a spot in Saturday’s Champions League final against Barcelona - United only managed to finish fourth in the Premier League.
Pogba failed to break into Sir Alex Ferguson’s first team plans before he left the club but nobody could have predicted his rise to stardom since moving to Italy. He is one of Juventus’ key players as they hunt for Champions League glory and the first treble in the club’s history.
Manchester City, Chelsea and United themselves have all been linked with a move for Pogba in the past, in the Express, but it appears if he were to move on from Juventus, a switch to Spain would be the most likely option.
Former Chelsea midfielder Michael Ballack believes United made a huge mistake in letting Pogba go back in 2012 and that they must regret the decision at this point in time.
He told Sky Sports: “It seems like it was a mistake from Manchester [United] to let him go.
"He has this desire. His physical ability is there. He also has the nous to read situations, and to be in the box to score goals. He can still improve that, and if he does he can be an outstanding player.”
Ballack would know all about what it takes to be a world-class central midfielder after being a key figure at Bayer Leverkusen, Bayern Munich, Chelsea and with the German national team during his own fantastic career, and he is obviously a huge fan of Pogba’s dominant style.
Despite the fact Pogba’s Juve team go into the Champions League final as major underdogs, Ballack believes there is still everything to play for.
He continued: “Barcelona will pay a lot of attention to themselves, to make their own game so that it runs with offensive, attacking football – with Messi, Neymar and Suarez up front.
“Juventus is a really strong opponent. They’re like Italian teams usually are; tactically very well educated. So it’s not like Barcelona are the better side, they are the big favourites and they will win it. I think it’s quite even.”
