I score from long shots quite regularly (Draxler, De Bruyne, Reus, Benteke and Pogba are quite good), as well as from through balls with Lukaku and Benteke finishing most things. I'm also pretty good at corners and crosses in general (again, Benteke is good at that.) However, I NEVER score free-kicks. In my fourth season of career mode I've never scored one.
Most of my goals come from the wing. I play as Villa almost exclusively so getting balls into Benteke is the easiest way to buy Fifa 16 coins. I tend not to play the lofted cross though. I normally choose to cut inside and play a chipped cross, it tends to land in a goal scoring position most of the time.
When Benteke is injured which happens a lot, at least in my seasons, I play through the middle. Delph is great for those dinking runs and playing through balls to Kozak. If that fails I score from range quite often. Players like Bacuna and Okore seem to hit the net most of the time if the ball falls to them around the edge of the area. I think in my last season Bacuna was my second highest scorer with 11 goals and all of them were long range efforts.
In my Cardiff career mode I don't tend to get alot of goals from crosses into the box since my wingers tend to cut in alot, Zaha, Bakkali and Daehli. I also tend to play more through the middle with Alberto and Barkley operating behind the main striker, playing lots of through balls and linking up. Majority of the goals come centrally or from long range efforts. Its very rare I'll score from a corner, or a crossing free kick, maybe 3 or 4 a season at most. I could also count on one hand the amount of direct free-kicks I have scored this years game, can never manage it.
My goals come from varied approaches also, I tend to though, run down the wing cut inside and either pass to a man on the edge of the box or a cross for a header or a tap in. I try crosses also without cutting inside - probably score more goals that way to earn Fifa 16 coins. I attempt few shots outside the box - only when it feels right and some do pay off. Corners I'm normally good at but haven't scored one in a while. I try attack through the middle also but most times I end up on the wing as teams normally play with a holding midfielder.
Now I try to completely dominate possession and make a huge amount of 'pass and move' style runs working my way into the box/onto the wings.
Basically I try to draw their defenders towards the passer, give and go, then the original passer receives the return ball in space and can shoot. Basically it's a patience game waiting for the right run into the right space, then playing the through ball.
If that seems to be failing, there is plan B - counterattack down the wings and cross to a high work rate striker/cut in if past the last defender and finesse into the far corner
