Top 5 players who left on a free transfer

#3 Paul Pogba - Juventus

AC Milan v Juventus FC - TIM Cup Final

Paul Pogba has not lived up to the lofty expectations that preceded him when he re-signed for Manchester United a few years ago - however, no one can debate the impact the midfielder had in Italy.

The French midfielder came through the ranks of Manchester United, ut was unhappy with the lack of playing time and opportunities at Old Trafford. In 2012, then manager Sir Alex Ferguson confirmed that Pogba had left England for Juventus. Although adamant about his decision to let him go, maybe Ferguson did regret his choice a few years down the line.

Pogba shone with his new team. The World Cup winner made 178 appearances for the club, scoring 34 times and assisting 43 goals. He won the Serie A four times and managed to reach the Champions League final in 2015 - all by the age of 23. If that was not enough, the money which Juventus made off of Pogba's return to Manchester United speaks volumes - an £89 million return on a zero investment.

Pogba is easily one of the greatest free transfers of all time.
