This is the weird formation used by my opponent. Please tell me how to counter it and give me the orders.TQ

Cant help with order or counter, but that IS illegal, no winger on right. So you should have possession advantage.

It's illegal. If you play with a legal formation and your opponent isn't much better than you, you probably will win. You can play with 4-5-1V.

but he won his recent 5 match.... its impossible to win it if it is illegal
