When I wrote the first part of this guide, I was half-way through my second season in charge (first FULL season) and was top of Div 5. I went on to win the league and the Dept cup that season. My team didn't concede a single goal in the League all season!!!
It was a very different story the next season as I finished 3rd from bottom of Div 4 and got relegated automatically. We bounced straight back up the following season, doing the double again, but the game engine had changed and we lost a few matches on the way.
I mention that because some of the game engine changes that were implemented between my first and second promotion seasons mean that I would recommend adapting your tactics slightly.
Firstly, the game engine now relies less on individual stats than it used to and more on the squad stats. The squad stats are the ones on the top-right of the Training page and are also represented by the series of stars at the bottom of the Team Info page for each team.
You can improve these by setting them in the training page - it's the four icons at the bottom of the panel on the right under "Current Training Program". Also, you can improve them further by buying weekend training camps.
I've found the training camps to be of little benefit. In order to get a big improvement on your squad stats, you have to select 5*, overseas, intensive, etc., which can work out at $6m+ per camp. If you do that every weekend in a season, that soon adds up and the stat gains aren't usually that great. You can also find that you ended getting stat gains in areas that you didn't ask for.
I prefer to boost the squad stats through training. The best way to get quick results is not to pick four different attributes to work on as this is painfully slow, but select the same attributes for all four choices - attack, for example. Within a couple of training sessions, you should start to see big gains in that stat and because they usually take a lot longer to drop down again, you can try to get that stat up to 85-95% before switching all four onto another attribute and doing the same.
Be careful not to let any particular stats get low.... 50 is the minimum I believe. You can switch them around as much as you want but I've found that leaving the 4 training attributes on one setting for several rounds makes it increase faster than keep switching them around. Also, bear in mind that training sessions happen only twice a day (8 UK) so don't expect instant results.
You'll find that the gains slow down as they reach 90+ and unless all your other stats are 90+ it's best to switch to another attribute to maximise the gains on that. Like I said, I've found that the stats gain quicker than they reduce.
You can also boost your training stat gains by improving your training grounds - you have to make a decision whether to boost your club's earning potential by increasing capacity and restaurant and club shop facilities or to improve your team's training facilities!
Initially, I spent the development time on increasing the capacity up to 20,000, which I've been able to fill for most matches. This gives me a steady income stream to keep the club in the black. Remember, that attendances in Div 4 & 5 go no higher than 30,000, so don't obsess about getting the biggest stadium money can buy just yet.
After improving the restaurant and club shop, I then focussed more on improving the training grounds up to the top spec as well as the Youth Academy, which will produce better young players each year!
The reason I did this was that I realised that although the older players are great in Div 5, when you reach Div 4, the level is so much higher and you'll need much better Q players to succeed there. The main problem with this is that I've found that in order to get promoted from Div 4, you really need a team of Q82+ average, but most Q80+ players don't want to move to a Div 4 team!
So, youth players really are your only option. Older players' stats will be dropping within a season or two and certainly won't be increasing, so you'll need the best players coming from your academy to get that Q82+ level needed to get promoted.
The hard bit to swallow is that unless you've already got a team of Q75+ 18 yr-olds, you're going to have to face being in an around Div 4 for a long time whilst your team develops.
OK, now I'm going to give you a few tips that I've either picked up from other guides/players or worked out myself.
Sponsorship
Look at all the packages and add-up how much you'll earn for a full season from each one. Bear in mind how you expect to perform in that season. For example, if you expect to do well in the cup and the league then go for the best overall package that also pays out for each cup round plus a cup winner bonus and payments based on final league position. If you know you're likely to get KO'd from the cup early on and you're probably going to end up in a relegation battle, then go for a package that pays out a high amount per round. Factor these into your calculations, so add up your initial payment, then the 'per round' payment x30. Then add in league and cup bonuses if you expect to do well, or leave these out if you don't. Be honest with yourself - if you've just been promoted to Div 4, then chances are you're not going to win the Division and do well in the League Cup. Likewise, if you've just been relegated from Div 4 and you did the double in Div 5 last time you were there, then there's a good chance you'll do the same again.
Credits
You'll find that you'll earn credits for various things and unless you use them for things like home friendlies or whatever, these will build up quite nicely over a few seasons. You can then convert these into cash - particularly useful if you've overspent on your next star striker and don't have enough to do that next stadium upgrade. Always try to leave yourself with at the very least 10 credits, just in case you need to use them.
You can also convert cash into credits and even buy (as in pay REAL money!) to get more credits. This seems to be what a lot of the top managers do to, which they then use to either buy over-inflated prices for players or for Home Friendlies.
Friendlies
From what I can gather, you are allowed to play 100 away friendlies every season for free and up to 200 home friendlies which cost credits. Most guides will tell you that you will need to use this full allowance up every season, playing your youth players in order to boost their abilities. I'm not denying this, nor am I approving of doing this, but I personally don't want to spend a fair bit of money on this game just to play friendlies. I won't slag off the players who do pay every month because they are the ones who subsidise those of us who play for free. However, it then begs the question - is it possible to climb the pyramid to Div 1 without buying credits? I'd like to hear from anyone who has!
That's enough for now. I'll give you more tips next time around and hopefully I won't wait as long to do so next time! ;)
