bish bosh,
I didn't borrow players from the established Classic team (though I edited in a few new defenders for England e.g. Pearse and Adams over Fenwick and Sansom).
I used Team Selection to insert the Retired Players into PES and WE Utd, then edited over a few of their fictional defenders to fill in the gaps left by the surplus of goalkeepers and OMF/CF's available in the PES shop....
PES Utd 'All-stars':
GK Yashin
CBT Aberlardo
CBT Zago
CBT Nadal
DMF Ince
DMF Dunga
CMF Effenberg
OMF Hagi
OMF Stoichkov
CF Dalgleish
CF Romario
Subs: Chilavert, Di Livio, Sampaio, Hernandez, Babangida, Palermo, Stoicjkovovic, Juninho P., R. Acuna, Metelger, Ravelli, Itsmona.
WE Utd 'All-Stars':
GK Jennings
CBT McGrath (edited over a WE defender)
CBT Hansen (edited)
LB Fashanu (editied - yes I was having a laugh)
RB Bremner (edited)
DMF Descinq
CMF Brady (edited)
RMF Best
LMF Scifo
CF Puskas
CF Eusebio
Subs: Preud 'homme, Anderson, Boban, Savecevic, Lima, Dennis Law, Ian Rush, Klinsman, Hugo Sanchez, Francescoli, Songo'o.
The point about the imbalance in Retired players available is important, I'd love to dump half the GK and CF's just to get classic DF and MF players. I had to add a few positions and manipulate abilities to allow some MF players to play at the back - e.g. Di Livio and Boban. The choices of retired players I edited in was very spur of the moment - if I could have spelt Goichacheia I would have put him in!
These were done on my original option file, but once I'd downloaded Georghino's option file the old PES teams appeared as normal. Where it changed those teams is in the Master League I started around the same time - these retired stars are now in the ML whichever option file I use - but I can put up with that.
Edited to add: Andoni Goikoetxea, that's how it's spelt - the “Butcher of Bilbao”.
