Jurgen Klopp has overseen a number of makeovers during his career, having revived the fortunes of Borussia Dortmund before bringing Liverpool back to the summit of English and European football.
He is the man who pioneered 'Heavy Metal Football' and champions the gegenpress at Anfield, doing so while sporting his own unique baseball-capped look on the touchline.
Klopp is not averse to personal makeovers either, admitting to getting a hair transplant in 2013 and anyone who has been paying attention will have noticed that his smile is brighter since arriving on Merseyside.
