1st are the players individually, in Q. terms, and how they are proggrammed of well, 2nd the formation.
Strong formations, that for me mean stable formations are formations with 4 defenses, and in ma ranking are the 4-3-3, 4-3-1-2, and of course, I dont use it, but 4-4-2 is one strong formation.
By my viewpoint 4 defenders + lot of people in the other side of the field to create how more posible options in attack is te key.
And till here my opinion lol.
