Stupid tactics from your opponent. well countered and played
when he conceded the 2nd goal, he changed to 4-3w-3 (and probably attack ment.) . That's a move that most of the managers do and it's butter on bread for the 4-5-1 def/counters. I don't agree with that.
The second mistake was that after loosing his player, he set 3DC instead of 3 defenders wide.
But, you know, the pressure is high and the clock is ticking
