Heh.
BTW, some useful information about training:
Passing training: trains passing and marking.
Short plays: trains reflexes and tackling.
Long plays: trains heading and speed.
Shooting training: trains shooting and handling.
So, what to make of this? If you look at the main stats of your players, you'd notice that the average rating of the different types of players is made out of three different stats. So if you want to improve the average rating, you'd have to train one of these stats. When you look again at the above list, you can see that these training forms are best suited for:
Passing training: midfielders
Short plays: forwards, defenders and goalkeepers
Long plays: forwards, defenders and midfielders
Shooting training: attackers and goalkeepers
Heading is good for scoring as well (duh). If the game makes any sense, heading for defenders would be especially good is the opponent plays with cross balls (a tactic that I'm about 100% sure of doesn't do a thing), and speed should be good for any player. Especially midfielders need a high speed rating. Long plays might be the best overall training form.
General training doesn't do very much either, but I've found that it's good to switch between training forms now and then. So if you're training forwards, train long plays for some weeks, then a week of general training, and then some weeks of shooting. That single week of general training allows for a lot of upgrades in stats that aren't trainend.
For instance, this week I changed from passing to general. One of my midfielders got a shooting upgrade. Unfortunately, it could have been that he'd have gotten a passing upgrade if I hadn't changed training. I doubt that though. I see it happen pretty often that upgrades are received when the training form has changed, so I'm pretty sure of this.
Any thoughts?
