Yeah, it's not easy, although to be fair we made a distinction between our playmaking central midfielders and box-to-box midfielders on a similar basis. You could split based on which forwards rely on their tehnical attributes moreso than their physical assets - i.e. if you had to choose what stood out most for each of these players between their physical and technical, you could split the list like this (Physical - Cristiano, Eusebio, Henry, Gullit, Rummenigge, Jairzinho, Keegan, Kubala, Bale, Salah, Blokhin, Heynckes; Technical - Messi, Baggio, Ronaldinho, Cruyff, Puskas, Di Stefano, Hidegkuti, Sivori, Savicevic, Rivaldo, Totti, Del Piero, Dalglish, Cantona, Albert, Neymar, Griezmann, Bergkamp). Although perhaps the cleanest solution would have been to throw these technical guys in with the list of 10s we've already done.
I'm not really arsed though, just brainstorming - good to hear other views.
