When it comes to being a successful football manager, tactics and man-management are key. 

There are several world class managers in football but only a few really know how to manage multi-millionaire players and their egos.

There have been times when the manager suddenly becomes a square peg in a round hole and the players stop responding to him.

In such cases, the club management has no choice but to let go of the manager as that is a much easier task than getting rid of high-profile players.

We look at five famous managers who lost the dressing room during their tenure at top clubs.

1) Carlo Ancelotti (Bayern Munich)

Until 2017, Carlo Ancelotti had never been sacked midway through a season.

No matter how bad things got during his tenure, he always sees out the campaign before moving on - Juventus, Chelsea and Real Madrid.

One of only two coaches to win the UEFA Champions League three times as a manager (the other being Liverpool's Bob Paisley), and having managed a host of top clubs, you would expect a well-traveled manager like him to have things under control when he replaced Pep Guardiola at Bayern Munich.

Bayern were supposed to improve on their semi-final finishes in the Champions League - the primary reason why Ancelotti was brought in.

However, all they won was the Budnesliga title in a league that has nobody to upstage them - clearly evident from the 15-point lead they had by the end of the season.

Players soon lost trust in the manager; most noticeably Arjen Robben, who did not agree with the number of minutes he was getting on the pitch.

Five players turned against Ancelotti and they included Robert Lewandowski and Thomas Muller.

The club were also not satisfied with the situation of things and had to let him go.

2) David Moyes (Manchester United)

Frankly, taking over from a manager such as Sir Alex Ferguson would be a nightmare for any coach.

David Moyes (The Chosen One) may not have been the first-choice but the club didn't have any other option at the time and decided to place their trust in an inexperienced manager to take the reins of the biggest football club in England.

It was an unmitigated disaster. Moyes had neither the presence nor the tactical acumen to lead the Red Devils to glory like his predecessor.

His small-club mentality and overly cautious approach when it came to making tactical decisions may have helped him at Everton but it clearly did not fit into the winning philosophy of the Red Devils.

Training sessions saw players quickly losing interest while players slowly became undisciplined - something unheard of during Ferguson's reign.

One player (a substitute) even encouraged the fourth official to send him off in a game where Moyes argued with the referee.

10 months after he was signed, Moyes lost his job when United were certain to miss out on the Champions League for the first time in years.

3) Claudio Ranieri (Leicester City)

Nobody deserved what happened to the veteran Italian boss. Here was a manager who had never won a top-flight league title in his career. 

And then he only went on to lift the Premier League title in his first season back in England when Leicester City's odds of winning it were an enormous 5,000/1.

In a season where all top clubs failed to wrest the initiative, Ranieri's Foxes went on an amazing run and did the unthinkable.

Nobody expected them to defend the title the next season as other clubs reinforced their sides but nobody predicted his fall from grace midway through the season either.

Leicester's poor form was reflective of the way the players were performing on the pitch. 

Star players such as Riyad Mahrez suddenly looked disinterested and did not bother listening to Ranieri's instructions. 

The team's slump saw them close to the relegation zone after which the management took the painful decision of letting him go.
