Choosing a modern day football manager can't be easy.
With hundreds of candidates to select from, fan expectations and the knowledge, the majority of the time, that is chosen must be capable of doing far better than his predecessor; it's an unenviable job to be had.
However sometimes it can be one that, if done properly, sparks a revival or change in fortunes that would otherwise be dismissable.
Here GMS contributor Ben Thornley honours that idea with his selection of the top five best managerial appointments of the season....
5. David Moyes - Manchester United
Ok, so the 50 year-old has struggled so far in his first season at Old Trafford, but in my mind this appointment will soon pay dividends.
Taking over from the great Sir Alex Ferguson was never going to be easy, but Moyes is a good manager who offers a great deal of consistency and as soon as he builds a world-class team at United, the Manchester club will be the most feared club in England once more.
4. Tony Pulis - Crystal Palace
Admittedly, Tony Pulis has never played the most beautiful football in the world, but he has always been a manager who has carved out big results.
When he took over Palace earlier on in the season, the south London club were rock bottom and were the clear favourites to go down. But after a couple of decent results, the Eagles are very much in the fight to stay in the Premier league, all thanks to the man now at their helm.
3. Manuel Pellegrini - Manchester City
Former Malaga and Real Madrid boss Manuel Pellegrini already had a world-class squad when he was appointed City manager at the start of the season and so far, his side have won every home game they have played this season- including a 4-1 win against rivals United, a 6-3 hammering of league leaders Arsenal and a 6-0 crushing of fellow top dogs Tottenham Hotspur.
The signings of Alvaro Negredo and Jesus Navas have been vital in the team's success this season and they can fully expect to lift the Premier league title this campaign if the form continues.
2. Roberto Martinez - Everton
With long term manager David Moyes departing the club to join Manchester United at the start of this present season, Everton found themselves in the search for a new manager and Wigan's F.A Cup winning boss Roberto Martinez was the ideal candidate.
The Toffee's had always been a consistent team aiming for Europe but Martinez has got them playing beautiful football this season as they challenge for a top four place to qualify for the Champions League.
Nobody has really given his team too much of a chance this season, but they keep on winning and victories against Manchester United and Chelsea this season prove that Martinez's team are a side to be taken seriously.
1. Jose Mourinho - Chelsea
There really was only one winner wasn't there?
Since Jose Mourinho left Chelsea in 2007 after a successful three-year stint in which Chelsea won the Premier League twice, no other manager, with the exception of Carlo Ancelotti in 2010, has delivered a title whilst at Stamford Bridge.
And in the eyes of club Captain John Terry, the Portuguese tactician has brought the fear factor back to the club. He is a born winner, having won the domestic league in Portugal with Porto, in Italy with Inter Milan and in Spain with Real Madrid as well as in England, whilst he has also won a variety of different cups to sit alongside his two Champions League titles.
Arguably the best manager in the world, if he does fail in his bid to win the Premier League this season, it certainly won't be long before he does bring back the big trophy to the Bridge.
