Player Position Training.

If you train a player to play in a different position, is it possible he will be a better player in that position?

For talking sake a ST with 9 finishing, but with 15 crossing and dribbling into a ARM. Will he be a better player because his attributed match his position, or will he normally be better in his natural position?

He will become natural in his new position if you train him and play him there I think

Very rare to become natural. He needs to have a high rating in the hidden attribute VERSATILITY. He can become accomplished which is almost as good as natural.

You striker example could become more effective as a winger, yes. Remember of course that how good he is depends on your whole team's settings, not just one player in isolation.

You can train a player to become natural, as contradictory as that sounds, but it requires training and playing him in that position for atleast a season with high adaptability players.
