Number 3: Shinji Kagawa (Borussia Dortmund to Manchester United)
Another massive signing from Germany, Kagawa impressed Sir Alex, with brilliant performances while at Dortmund and he was bought by United. He also was an important part of the side that won the Premier League in Sir Alex’s final season. However David Moyes failed to bring out the best in the Japanese star (among other things he failed at) and Kagawa struggled to find form and consistency under his new manager. He became a part-time playerAin the new United set-up and was rescued by Klopp and returned to Dortmund after only two seasons in England.
