Don't understand how chemistry in this game work at all. Can someone point me to a good place that describe how chem works in FIFA13?
Here's my update on Falcao centric team:

Saved up 19K then spend it on Navas(15.5K) and Tiote(2.3K). Then another 1.5K to convert both to the right position. The price for CDM >> CM is crazily fluctuated. I got mine for 800 but the one just before that went for 1900. Now it's really annoying that Navas don't get any boost from Falcao at all.
Ever since I switch to 3-4-3, Falcao is truly a beast. Love him so much now LOL.
Chemistry is down to a few things, personal chemistry goes up if players are in their right formation with their proper position.
They get a further boost by the players around them, this is what the lines are. Connected players get a boost if players play in same league, are the same nationality or play for the same club. Satisfying one of these gets an orange line (small boost) and two is a green line (big boost) - but a 9 maxes them out anyway.
So sometimes moving the same players around on a pitch will connect the right players leading to a boost to overall team chemistry which maxes out at 100.
There will be more exact formulas for how many players need to be 9 for your team to reach 100 but I've told you all you need to know.
Relate players to each other.
Falcao and Navas get the same league boost, changing Navas position had no effect on that, it's an orange line regardless.
Falcao playing in Spain has no effect on your GK's chemistry so you could get creative with how you mix and match players.
