The 2012/13 campaign will be known as the season that saw several changes in management at Premier League clubs, with many sides firing their existing bosses and hiring new ones.

There was also the shocking news that Sir Alex Ferguson is set to retire as Manchester United boss which has also provided a shock to the footballing world.

The latest managerial sacking has come from Manchester as well, as City have just broken the news that Roberto Mancini will be leaving the club at the end of the current season after the club failed to win any silverware this season.

Last year's champions fell well short in the title race, as fierce-rivals Manchester United ran away with the title and then the club lost in the FA Cup final to Wigan Athletic - which seemingly was the last straw in Mancini's career at the Etihad Stadium.

It was just a year ago when Sergio Aguero scored a 90th-minute winner to secure a Premier League title for City which put Mancini in City's history, but winning nothing this season has evidently lost him his job.

Mancini hasn't been the only surprise sacking though this season. Here are a few more that have shocked the footballing world.

What about Chelsea's decision to sack Roberto Di Matteo in November after the side got knocked out of the Champions League group stage? 

After guiding the club to FA Cup glory and also Champions League glory, for the first time in the club's history, the Italian got the manager's job on a permanent base, but then lost it just months later.

After performing badly in the Champions League, Roman Abramovich took the decision upon himself to fire the fan-favourite manager and replace him with interim-manager Rafael Benitez. 

Then there was the sackings at the bottom of the table. In particular the sackings of Southampton's Nigel Adkins and Reading's Brian McDermott.

I must stress now the sacking of Adkins seems like a great bit of business from the Saints, as his replacement Pochettini has done wonders at the St Marys, but at the time of the sacking, it was labelled as a terrible decision.

The club were above the relegation zone and Adkins had guided the club from League 1 to the Premier League in just two years. 

As for McDermott, he had previously won the Manager of the Month award, but was then sacked the month later after Reading were placed at the bottom of the pile in the Premier League.

Despite being at the bottom, McDermott had done a great job at Reading and was loved by the fans, but the club took it upon themselves to sack the manager and hire Nigel Adkins as his replacement. A change that didn't help prevent the club from being relegated.

So from the retirement of Sir Alex Ferguson to the sackings of; Roberto Mancini, Brian McDermott and Nigel Adkins, this season has been quite a shocking one in terms of managerial vacancies.
