We should be playing our best players who happen to actually link up well together
Fuck the argument of balance. The '1' in a 4312 is an offensive player first, defensive second. And Berna is fucking absolutely useless in attack.
Imagine Barca benching one of Messi, Neymar or Suarez back in the day in favour of somebody like Berna. Wouldn't fucking happen. Why would you purposefully choose not to play your best players that also work well together?
