There are managers out there who have won precious little - but still rank among the greatest managers of all time.
Guy Roux is one example. As boss of lowly Auxerre in France, he only won the one Ligue 1 title. Why Roux is quite so revered, however, is more down to the fact that he coached his side for over 40 years in three spells. It's hard enough supporting a club for that long with little to no success - let alone managing them.

Today, we're looking for the managers who can be considered the most successful in the world, judging by their trophy haul. We've listed all the major gongs we can think of - how many of their winners can you recall?
