Pep Guardiola and Jurgen Klopp will meet again on Tuesday night, with a place in the semi-finals of the Champions League up for grabs.
The duo, of Manchester City and Liverpool respectively, faced off in the quarter-final first leg last week, where the Reds cruised to a 3-0 victory at Anfield.
The two managers have quite a bit in common - they have managed in England and Spain, are successful and popular characters and, most of all, they hate losing.

Guardiola has managed Barcelona, Bayern Munich and Manchester City, overseeing some fantastic sides since taking over at the Nou Camp a decade ago.
Meanwhile, Klopp has only managed Liverpool in England, after starting out at Mainz before helping Borussia Dortmund to the Bundesliga title and the 2013 Champions League final.
