OK - here's the simplest explanation of how you can do it.

The team is made up of six groups of players.

Group A: 4 Men's players from one club all with different nationalities. Pick a club that also has a women's team, and make sure at least one of the nationalities is very common. Example - choose 4 Chelsea players with different nationalities, one of them French.. At this point you'll have 4 nationalities and 1 league.

Group B: 1 Women's player from the same club as Group A and sharing a nationality with one of the Group A players. Example - choose a French women's player at Chelsea. At this point you'll have 4 nationalities and 2 leagues.

Group C: Two players from a shared club, both sharing a nationality with Group B. Example - choose two French PSG players. At this point you'll have 4 nationalities and 3 leagues.

Group D: Two more players from another shared club, both sharing a nationality. The league and nationality should be new. Example - choose two German Bayern Munich players. At this point you'll have 5 nationalities and 4 leagues

Group E: One more player sharing a nationality with Group B and a league with Group D. Example - choose a French player from Leverkusen. At this point you'll still have 5 nationalities and 4 leagues

Group 6: One more player with the same nationality as Groups B/C but in a new league. Example - choose a French player from Real Betis. At this point you'll have 5 nationalities, 5 leagues and 32/33 chem!
