Barca FC
It's not a show off as under any circumstance, I just want to prove my point here. As you can see below, I used the same formation as my opponent in CL. I also used 6-7 reserve players. Away match 0-8, I used M2M and whole pitch, it seem to be very effective even I wasn't there. The total shots and (shots on target) 36 (15). On the opposite side of it. At home 4-0, I used zone with own half, my team scored only 2 goals...until I showed up around 56' and switched to M2M, then my players controlled the match and scored 2 more goals. The total shots and (shots on target) 15 (7).
...what about your player's condition at the end of those matches?
I suppose this requires a lot of spending of it...
