4-1-2-3 Illegal formation?

[Berko]

Can't see anything wrong with that one - 4-5-1 V should do okay though. If it was illegal you'll get 80% possession!

TY, for your reply.

Based on illegal formations thread, I thought it must have at least 2 players in each side flancs, but obviously I was wrong.

"At least 1, but no more than 2, players on EACH outside flank. {the D(L/R), DM(L/R), M(L/R), AM(L/R) slots}"
