There are lies, damn lies and statistics. Or so it is said (although usually without any data to back up such a claim).
Ask a statistician however and he/she will tell you that there are statistics used properly and statistics used improperly or with incomplete data. Football, sadly, is fully of the latter two groups, and we seem to have just been offered another batch of such “analyses”.
The CIES Football Observatory has an impressive name, and appears to present serious data. Its academic credentials look impeccable working as it does within the International Centre for Sports Studies which is promoted as “an independent study centre located in Neuchâtel, Switzerland.” It claims a staff of four full-time permanent researchers who specialise in the statistical analysis of football.
All well and good and presumably highly believable. But why then does it keep coming up with figures and statistics that I find hard to believe?
Undoubtedly many will think it is because I am a rabid nutter who not only can’t proof read but also can’t add up. But stay with me for a moment because although such comments might be valid, I think there is something else going on here.
The answer, in terms of the Observatory’s analyses is, I think, that there is nothing wrong with their original data, but there is something amiss with their presentation. For so keen are they on the headline grabbing stats that sometimes a little of the vital background information gets, well, sort of… lost.
For example they are currently trumpeting an analysis of the age of player recruitment by clubs, and they say that “Real Madrid squad members were on average recruited at the age of 22.5 years,” which is apparently the lowest figure at big 5 league level. They then go on to tell us that “the best clubs focus their recruitment on younger players than less competitive teams. In the top five positions of clubs whose transfer policy is most centred on young footballers are four Champions League participating teams: Real Madrid, Leverkusen, Dortmund and Tottenham.”
So no Arsenal. I find that a bit surprising. In fact Arsenal are not even in the top 10, although Bournemouth and Liverpool are. In fact Arsenal are shown as having an average age of recruitment of 24.07 years, compared with 23.35 years for the Tiny Totts.
That just doesn’t seem right to me from what I know of the two teams. So time for a bit of digging.
In another analysis presented at the same time by the “Observatory” there is an analysis of the type of recruitment used for players in the squads of teams, shown by leagues. In the Premier League the numbers are broken down into four groups
- Internal promotion 8.5%
- Loan from another club 3.7%
- Free Transfer 16.6%
- Paid Transfer 71.2%
What makes that interesting is that for Arsenal, in a squad of 30 first teamers such as Arsenal have (that is the club’s official figure – the 25 players registered as their first team squad who are over 21, and five players who are under 21 who are considered part of the first team), a fair number joined as youth players including…
|1||Kieran Gibbs*||LB||26 Sep 1989|
|2||Aaron Ramsey*||Mid||26 Dec 1990|
|3||Theo Walcott*||Forward||16 Mar 1989|
|4||Alex Oxlade-Chamberlain*||Mid||15 Aug 1993|
|5||Carl Jenkinson*||RB||8 Feb 1992|
|6||Emiliano Martinez*||GK||2 Sep 1992|
|7||Francis Coquelin*||DM||13 May 1991|
|8||Matt Macey*||GK||9 Sep 1994|
|9||Yaya Sanogo||Forward||27 Jan 1993|
Plus all the under 21s included in our First Team Squad
|10||Rob Holding*||CB||12 Sep 1995|
|11||Alex Iwobi*||Forward/MF||3 May 1996|
|12||Hector Bellerin*||RB||19 Mar 1995|
|13||Chuba Akpom*||Forward||9 Oct 1995|
|14||Jeff Reine-Adelaide*||Forward||17 Jan 1998|
So that makes 14 out of 30 players who were recruited as youth players, or 46% of the current Arsenal squad. The players with asterisks are also considered “home grown”.
Thus Arsenal has an internal promotion level of 46% compared with the Observatory’s average figure for the Premier League of 8.5% and yet we have an average age of recruitment at over 24 years – putting us in the lower reaches of the league for youth recruitment. It just doesn’t add up.
In fact it seems quite ludicrous, and the problem is there is no sure fire way to resolve the anomaly because CIS simply don’t provide (at least anywhere I can find it) an analysis of how they are compiling this data.
What I think is happening (but I stress this is a guess because the data is not revealed) is that they are only counting players who are brought into the club as paid transfers. So a player like Kieran Gibbs who joined Arsenal at the age of 15 is not counted anywhere at all in the chart. Rob Holding might be counted because he has gone straight into the first team squad, but Hector Bellerin who joined aged 16 is not because he went into the youth team first. There are of course many such examples of players who, through this sort of approach, are simply not counted.
I stress, that is what I think, and I can’t be sure because CIS is not releasing the information we need to find out what the figures make no sense. And that is the biggest problem – data without a full explanation of how it was gathered.
The point has some importance when the aaa and their allies in the media start their ranting along the lines of “spend some ******* money” (sorry I know that you know what the word is, and putting a load of asterisks in is a bit pathetic but apparently if I write it, then the news now corporation might well not print a link to this story, and then I get emails asking why we are not on their feed and …. well it’s all a bit of a pain) the whole analysis of how many players Arsenal buy is based on the premise that only players who cost money and go straight into the first team squad, actually count. Which is a nonsense.
Arsenal are using a totally different approach, of bringing in young players and promoting them through the ranks. It is a perfectly valid approach – but just doesn’t fit in with the CIS definition of how things should be.
It is a shame that CIS are not giving us clear information about how they do their analysis (or if they are that they are not giving links from the analysis to the research details, so I can find it all). This type of information is useful – but in its present form it is quite possibly misleading.
