I have 7-8 triple position players. You just buy a double position nordgen and add a 3rd. Especially if you get them at 3-4* this is easy.

I have both FB's that were FB/CB, very good value, 3*, but wrong footed. I added the correct side to them and put them out there.

Training to 9* is either very expensive, involves tanking a couple seasons, or a ton of farming (beyond what is available in US). It doesn't mean cheating. It could be possible, but I am a good programmer and know hacks.....it is not so simple to do and especially not to get quickly banned.
