basic description of 4-1-4-1:
1)has a back four(stable)
2)has a DMC to counter AMC
3)has a good number of midfielders to maintain formation
4)1 striker will coz few problems

The formation is quite balanced.i would suggest using formation like 4-4-2 or mirror his formation if ur better than him by playing down the flanks.4-3n-2w-1 is another option

Why 4-4-2
1)u will avoid his DMC
2)u will be able to play down the flanks so as to attack his full backs
3)u will have two central midfielders to match his 2 central midfielders.(excluding wingers)this means that u will be able to maintain possession.
4)u will have a back four to stop his wingers and striker

Why 4-3n-2w-1?
1)u will avoid his DMC
2)u will have three central midfielders versus his 2 midfielders.
3)u will have two wingers I pm advanced positions to attack his full backs.
4)u will have one striker who will be supported by ur wingers.

My preferences:
1)4-1-4-1 if ur better
2)4-4-2
3)4-3-2-1
