3. Paul Pogba: Manchester United to Juventus
After joining Juventus from Manchester United on a free transfer, Paul Pogba went on to establish himself as one of the best midfielders in the world during his four-year stay with the Italian giants. Pogba, together with Andrea Pirlo and Arturo Vidal, helped Juventus create an impenetrable midfield.
He became a key part of Antonio Conte's plans and started getting more opportunities to impress. The French midfielder made 178 appearances for the Turin club, scoring 34 goals and registering 43 assists as he won multiple trophies with the club, including 4 league titles.
Along with the team honours, he was also named in the Seria A team of the year for 3 consecutive years and won the Golden Boy award in 2013. Ironically, Pogba returned to United in 2016 for a then world-record fee of £89 million.
