4-4-2 Diamond numbering system/numbering systems in general

I coach HS soccer. My fellow coaches and I have decided to move to a 4-4-2 with a diamond midfield from a 4-4-2 flat. We also decided to use a numbering system for positions instead of names. While researching I discovered 2 different numbering systems for the 4-4-2 Diamond.
7 9
10
11 8
4
3 6 5 2
1

and

9 11
10
7 8
6
2 3 4 5
1

Which is correct?
