its same PTCR, under 29, same position. Homenations. Will not sell real life Man City players under 26.
So, for example to swap in Aaron Lennon, you'd need Adam Johnson...or maybe SWP
So swap in Arteta, you'd need a 9797 PM, under 29, a Carrick or Modric or someone like that.
You cant swap one of there English players for a foreigner either. You can however swap foreigner for foreigner.
