Is Sacking a Manager really that bad?
Every season a manager gets sacked and the press run with a very familiar line “his sacking was unfair” or “poor decision by the club’s board to sack [manager x].” However is sacking your manager really a bad thing? Using data from only the past 3 seasons (excluding this one since it is too early) I analyze (i.e. let graphs do my analysis for me) their points per game ratio and if sticking with the original manager would have affected their season.
Firstly the managerial sackings I considered and didn’t:
- Chelsea 2008/9. Sacking Scolari and appointing Hiddink (Considered)
- Blackburn 2008. Sacking Ince and appointing Allardyce (Considered)
- Portsmouth 2008. Replacing Redknapp (not a sacking) with Tony Adams (then sacking him). Not considered (That wasn’t done on purpose (appointing Adams) so not suitable)
- Tottenham 2008. Sacking Ramos and replacing with Redknapp. (Insert triangle joke here) Also not considered due to not enough games and Spurs just being woeful that season.
- Hull City 2009/10. Sacking Phil Brown and bringing in Iain Dowie (!!!!!). Normally I wouldn’t consider it due to it being less than 10 games but I wanted to see if it effected their relegation. (Considered)
- Bolton 2009/10. Replacing Ginger Mourinho Gary Megson with Owen Coyle. This was almost always going to be considered.
- Burnley 2009/10. Brian Laws coming in for Coyle. Not considered as it wasn’t sacking.
- Manchester City 2009/10. Hughes sacked for former Leicester City player Roberto Mancini. Considered.
- Portsmouth 2009/10. Sacking Paul Hart for Avram Grant. Considered due to the fact I wanted to see if Grant’s record was actually “miles better” as I read somewhere.
- Newcastle 2010/11. Hughton out for Alan Pardew. Considered wanted to see if Mike Ashley was right.
- Blackburn 2010/11. Allardyce sacked in favour of Steve Kean. Considered – long live the Venky boys
- Liverpool 2010/11. Roy Hodgson sacked for “King” Kenny Dalglish. Considered
- West Brom 2010/11 Di Matteo sacked for Roy Hodgson. Considered
Two of the above I have gone into more detail and compared their records this season (which I will explain later). Liverpool and Bolton but as I said I will explain this later.
Pre sacking Ratio v Post Sacking ratio
I am not putting in the names of the managers as there were probably care takers involved. My main aim is to see if a sacking had or didn’t have an impact. So here is the overall graph of the managers above who were considered:

Is it really that bad?
As you can see from the graph above there are only two instances where sacking the manager has proved to be detrimental (Blackburn 2010/11 and Hull City 2009/10), below is the actual figures of the points per game:
| Pre-Sacking Ratio | Post sacking ratio | |
| West Brom (2010) |
1.04 |
1.615384615 |
| Liverpool (2010) |

1.96 |
2.615384615 |
| Blackburn (2008) |
0.764706 |
1.333333333 |
Chelsea improved almost by a whole point under Hiddink as opposed to Scolari whilst Coyle’s renaissance wasn’t as good in his first season with only a 0.05 difference to Megson’s.
Did the sackings have an impact on the final positions?

Here the first column is the team, second column is what the final number of points would be if they hadn’t sacked the manager. The third column is the points accrued after the managerial change. The 4th column is what the team’s final position would be if they had stuck with the original manager (here if it ended at 0.5 or close I rounded up and down). The last column was the actual position.
The most stunning differences concern Blackburn (surprise!). In the 2008/9 season if they had persisted with Paul Ince till the end of the season then, judging by his points per game performance, he would have lead Blackburn to 20th place in the table with a 12 point difference to their actual final position of 15th. Also last season they would have finished in the top 10 with they had not sacked Sam Allardyce.
West Brom would have also been relegated if they hadn’t sacked Roberto Di Matteo. Although it says 16 or 17 on the table above, if they finished 17th their goal difference was almost identical to the team the team that finished 18th (Birmingham).
More interestingly the table shows that two “bigger” clubs, Chelsea and City, gained more points under their new managers but would have ended in the same position. Many things affected this such as, certainly during the 2008/9 season with Arsenal, teams around not doing so well or vice versa teams around them doing spectacularly well.
Bolton & Liverpool: Then and Now
Bolton and Liverpool have intrigued me the most this season with their varying fortunes. So I decided to take a look at Bolton’s games this season to see where they would have been under Megson and the same for Dalglish and Liverpool. Table below:
| Points under old | Current points | Position with old | Current position | |
| Bolton |
29 |
26 |
16 |
17 |
| Liverpool |
37.5 |

Certainly with Bolton that isn’t much of a difference as Coyle’s current points per game is slightly below Megson when he got sacked (omen?) though I suspect Liverpool fans can be vindicated with the club’s decision to sack Roy Hodgson.
However this doesn’t take into account, obviously, money spent by managers and that relative to position.
Overall, you could say in certain circumstances managerial sackings certainly have virtually no impact on final standings but my results do show that in most occasions a managerial change usually results in more points gained per match which can only be a good thing. But these are only results for the past 3 seasons if I were to go into more detail and go further back it would, in fact it should, even itself out, what with the law of averages and all.
In parting I would just like to give my best wishes to Eric Abidal, Fabrice Muamba and Stylian Petrov and their respective families.
