Borussia Dortmund v Tottenham Hotspur - UEFA Champions League

The wonder boy from Japan joined United on a 4 year deal after 2 successful seasons in Borussia in 2012.The goal scoring midfielder, with his nimble feet and deft passing was expected to be the next Park Ji Sung.

However, during his 2 years at United, Kagawa mostly flattered to deceive apart from standout performances in a few games. With the arrival of Juan Mata, he had no choice but to leave for his former club, where he continues to pull the strings of the attack.
