While it is clear that every manager in world football is under pressure to perform, the expectations placed on them by owners can vary drastically.
For managers of the major European heavyweights the pressure is enormous with owners and investors expecting an immediate return on their investment.
A prime example of the transitory, trophy-dependent life at the top is that of Carlo Ancelotti at Real Madrid. After having led the world's largest and most illustrious club to their historic tenth Champions League title, one barren year was all that was needed to undo the hard work. It's tough at the top.

A close eye will be on Rafael Benitez at Real Madrid this year as he strives to reclaim the La Liga and Champions League titles from the Catalan giants, however, it will be Frenchman Laurent Blanc who will be under the most pressure to perform this season.
PSG's money-inspired success has been widely documented, securing three Ligue 1 titles in consecutive seasons, but it is easy to forget their stuttering history of relative mediocrity as they watched the likes of Lyon and Marseille dominate the French game for decades.
Money really does talk, and thanks to the 2011 takeover from Qatar Sports Investment PSG are a now a regular fixture at the summit of Ligue 1 and the latter stages of the Champions League.
But with investment comes expectation and after establishing themselves as the best club in France over the past three seasons, the pressure is really on for Laurent Blanc to improve upon his record of two successive Champions League quarter-final exits.
Club president Nasser Al-Khelaifi will wait in expectation for Les Parisiens to go one, or ideally two better this year and reach the semi-final or final of the world's largest club competition.
Last season David Luiz was brought in as the marquee signing for an extortionate £50 million, and this summer has seen the arrival of another world-class talent in Angel di Maria for a reported £44 million.
Unlike Luiz who was purchased in order to form a defensive axis centred on strong and pacy Brazilians with Marquinhos and Thiago Silva already on PSG's books, the Argentine is a real game changer and is a player with undoubted Champions League pedigree, having produced a man-of-the-match performance in Real Madrid's aforementioned 'La Decima' title victory in 13/14.
Blanc's contract expires at the end of the 15/16 season. At the time he signed the contract he said: "I want to be part of this project over the long-term, the most ambitious project in European football".
The Frenchman has a squad of talented players whose average wage is greater than that of any other team in the world, has a beautiful modern stadium, and some of the wealthiest and spend-happy owners in the game.
Laurent Blanc needs to deliver Champions League success this season. If he fails, the patient Qatari owners may be forced to look elsewhere for a coach to spearhead the most ambitious project in European football.
