Study one
Study two
Study three
It's reasonable to expect a footballer to turn in strong seasons at the age of 28 or 29, but if you're hoping for them to still be on an ascending trajectory at that age you're essentially hoping for a fluke.
And again: the point I'm making is that 27 is the
youngest signing (Gana, maybe Schneiderlin) of the Koeman/Walsh/Moshiri era. It's not a sustainable model.
Ok mate, you know what those studies from briefly skimming them show me, the following
One is using the whoscored website as the index to calculate a players overall performance and at what age
Another is using minutes played as its basis for calculating the peak part of a career age wise
And the cartalige free captain one - again uses minutes played and its sample range is from 2011/12 season until the article date of december 2013
as for 27 being the youngest signing, errrm actually it isn't mate, we brought a striker on last night who we got this sumer and he is just 19
are 'older' signings are in centre midfield, centre back and goalkeeper, and a winger, the positions that tend to age fastest are wigners, fullbacks and strikers
ofc none of that takes into account the style' of the player, people relying on certain things and attributes age faster, one 27 yearold like Gibson is probably in a much worse physical condittion than say the average 32 yo player
Just looking at a study and thinking it gives the answers is frankly a bit silly, it's why moneyball transcribed over to footy will ultimately fail badly
