Is this possible?

I have player (Eyong Enoh) and he stats for a centerbak . Is it possible to make him play there?

Yes it is. Click on the player, then on the training overview there's an option where you can train to any position you want.

Yeah just play him in that position. You can also train him to play in that position.

Can take a long time, but it can be done. On the other hand, why would you do it, it is not that he will be an instant CB to cover for injuries or so?

As has been said you can train him to play DC. I have a policy in my game to train players for new positions if I think their stats suit that position. In 1 1/2 seasons I have managed to train at least 3 or 4 players to being good enough to play regularly in that new position, and many others can fill in if needed to.

It depends up on a players adaptability as to how long they will take to fully learn the new position, but you'll get the usual guide as to how able they are; i.e. ineffective to natural. Never seen anyone become natural, and I assume they never will.

I don't know of any fact in this, but I try to train players to a position that is similar to their current. For new DCs I choose DMCs and for new AMC/FCs I will choose current MCs. I've never seen a striker become an able DC. I'm sure it's possible though.

If you train striker to be a dc and if he has low defending stats than all his attacking stats will rise without using CA.
