The middle must be $7$, as the outside is all given as $\{1,2,3,4,5,6\}$


The innermost circle (around the $7$) could be a rotation by two positions of the outermost circle in either direction, with the remaining six entries (the big inner circle, near the outside) a "rotation" by two positions in the other direction (see below).
The other option that one might want to try is to have the innermost circle opposing the outside one (or rotated by $3$), but the big inner circle wont work in that configuration.
