Work on your tactics, read more on tactical suggestions for those formations and play some friendlies to know which is best for your team. Playing down the middle like you did in that match was wrong, it should have been through the flanks. And most people using 4 5 1 has suggested it is a defence/counter formation. Infact I don't play down the middle it looks a bit clustered for me. I play 4 4 2 mostly and its down the flanks and short passing most times .
