Hahahahahha....... It is an illegal formation!!!!! LOLs mate u need not worry. He will have only 20% possession as he had only 2 Defenders when he needs to have at least 3. Ya, u can still lose as this is T11. And I think Boyscout didn't see this properly otherwise even he would have pointed this out.
Play 3N-1-3W-1-2 through the middle. Or u can play 4-5-1 V with mixed passing. All the best. Field ur best players and u shall win with a big margin. :-)
