Jurgen Klopp caught almost everybody off-guard when he announced on Friday that he will be leaving Liverpool at the end of the season after nine years on Merseyside.

Xabi Alonso, Roberto De Zerbi, Ange Postecoglou, Thomas Frank and Julian Nagelsmann have all emerged as potential candidates, but who would be the best option?
