It's a bit of a long process, but it can be done. We'll use Ronaldo as an example.
1. Do a 'Base Copy' of Ronaldo from Brazil's national team and store him on your memory card. Write down his appearance and stats on a piece of paper.
2. Then go to Real Madrid and edit a player that no longer plays for them (or someone that really won't be missed) and change him into Ronaldo. Press confirm.
3. Now go to Inter Milan and change Ronaldo into someone else that now plays for Inter. Most players at this level are in the game somewhere, so just write down there stats and repeat the process. Otherwise look in the 'Player Creation' section here on PESInsight and get it from there.
4. Now go to Brazil's national side. Ronaldo is now the new player you created in Inter. Not good. Now just take your saved Ronaldo and put him back into Brazil
over the imposter!
5. All done
Hope this helps!
P.s Elfsborg eh? Vilken del av Sverige kommer du ifrån?
