Finally that coward has been punished. In this duel all conditions were on his side and he couldn't win. Mou doesn't know to play attacking-style football. His teams win matches against weaker opponents just because quallity difference, but against strong teams he would always defend. He doesn't want to be favourite against top rated teams. This time his opponent was quite strong, but opponent who refused to be favourite. Mou had to attack, but he couldn’t cope with the pressure, not players..
I'd like to compare that duel with this season's League Cup semi-finals Liverpool - Chelsea. 1st match was on Anfield, 61% ball possession for Liverpool, 13 shoots, 8 on goal while Chelsea had 2 shoots, one on goal, and that goal was scored from penalty. Only difference between that match's line-up and this match was on DL (then Filipe Luis, now Azpilicueta). Then he had luck, Liverpool deserved to win, but you can't have luck every time.
Finnally Mou has no excuses. He isn't that good manager, PSG proved it.
