If a must, I prefer a monster of MC, I have legend MC last 5 seasons with dribbling SA and he's been a monster, raking in at least 50-60 goals and assists per season. My team always have 6* GK, 7* DC, 9*MC, 8*AMC/ST and 6*ST. reason I say the middle spine needed as strongest because no matter what formation you use, those players always play, as for wingers, not always needed when you play formations such as 4-1-2-1-2 or 4-3-3 or 4-3-1-2. Invest in players that will sure start in every formation is more practical.
