The international coaching carousel is in full swing. Jurgen Klopp was officially unveiled as Germany head coach on Friday, tasked with reviving a national team that has struggled to recapture the heights of its 2014 World Cup triumph. Italy have also turned to a legend, appointing 2006 World Cup winner Andrea Pirlo to lead the Azzurri as they look to end years of disappointment on the global stage. And in France, Zinedine Zidane is expected to be named Les Bleus' new head coach on Tuesday.
