This is why for me the new owners will most likely be replacing / demoting the likes of Murtough and put more competent individuals in charge to spearhead the recruitment and have a decisive strategy over the coming seasons. It's a really poor reflection that a new manager comes in and although the likes of Kane, Kovacic etc raise the teams performance levels drastically their age profile represents a very dangerous trend of lacking any foresight to build an established team over the course of time.
I think what Madrid have done with Valverde, Camavinga and Tchouameni United need to take a page out of the same book and build for sustained success not short term fixes. In 36 months pending declines and high contract negotiations it will be hard to shift some of these players with the ridiculous strategy.
Another way to look at it, is having a very strong squad built for winning in the near future whilst buying time to purchase replacements who can then slot into a vehicle already motioning towards success and a culture of expectations and standards.
You mention Madrid, but it should be noted they are much further along the outlined model so can simply purchase the best of the best youngsters coming through, no bother at all whilst those same talents won't look in this direction until we too can offer them stability and an assured culture of winning and success.
We've got to start somewhere, but all avenues have their pros and cons; buy young, and you have to factor in growing pains, maturity and development issues as well as the current squad potentially decaying in the interim.
The lines are very fine and so are the margins for error - age profile should obviously have merit, but so too should have the right mix of experience, know how and downright, ready to go competence, which we as a squad are only now getting to grips with thanks to the acquisitions of the older heads who are steadying the ship this season.
