I have no idea where to we could find them but I bet there must be articles out there that suggest the more successful sides always have a higher average age but with a good mix of youth and experience.
I love the fact we seem to have started producing our own first teamers for the first time in what seems like forever, but I wouldn't get carried away too much just yet. Maybe fast-forward and the prospect of having some home grown players of all ages throughout our squad, that is something I could get much more excited about. Imagine still having 27/28 year old Mason, Kane and Bentalebs mixed with future waves of youngsters coming through looking up to these guys as roles models and proof of what could be... as opposed to the general feeling of 'Try as hard as you like but eventually after a few loans, if you don't breakthrough it doesn't matter as you will always have the fall back of knowing some football league club will pick you up'
