Some good words of wisdom from the Doc there.

There's quite a fixation with young talented players in this game which has always amazed me considering how long in real time they take to develop even if you have the full facilities.
I've had an alternate (from the norm) view of the game since I started.
Once I realised how the leagues were structured I decided my number one priority was to get promoted to the top division asap. Stadium building came second and young talent a distant third.

Why? Because new human teams start in the low divisons and the higher divisons were mostly full of bots. Bots are much easier to beat than humans. So it's easier to promote now rather than in a few seasons when the higher divs will have more humans and promotion will be much more difficult.

So my priority has been to buy players who would improve my team, especially high BPOS, regardless of their age. Some incredible bargains are available aged 25+ who still have 5 good seasons (thats nearly 2 yrs real time!).
Along the way I've slowly increased the stadium and facilities when funds were available and the next promotion assured. I've been here since season 1 but I won't have full vip+exec seats until my latest construction completes tomorrow! And I've slowly gathered some young talent. Next season I will be in the Top Div.
I'm not claiming the best strategy just showing that there are different
options available for new managers.

Well of course you are right, good management must balance finances whatever strategy you choose, and yes a stadium build is a good idea in the first few weeks.
However, good cheap players are available. I've recently sold 2 of my best players who were part of my promotions and last 2 cup runs. Total price for both players 21k! And the reason they were so cheap was because they were 29 and 30 yrs old, but they still have 1 or 2 good seasons left.
