#3 Henrikh Mkhitaryan
The Armenian joined Dortmund from Shakhtar as a replacement for Mario Gotze. He was impressive during his time at the Signal Iduna Park scoring 41 goals and further providing 49 assists during his three-year stay in Germany.
In the 2015/16 season, he was on top of the assists charts for Dortmund and was voted Kicker Bundesliga's Players' Player of the Season. He also won two German Super Cups with the BVB.
He revealed that he left Dortmund as he wanted a new challenge and even went on to say that that signing for Manchester United was a big deal, "Manchester United are a bigger club than Borussia Dortmund, everyone knows that and we should just accept that".
He joined Manchester United in the summer of 2017 and won the Europa League and the League Cup with them. But he could never cement his place in United's starting line up and was part of a swap deal that saw him leave for the Emirates and Alexis Sanchez moving to United.
