Congrats all the winners!
Penalty shootout in knockout stage hasn't happened for ages, watched some few games and fell asleep half way. No entertainment, no dangerous attacking, no intensity, just low block teams playing deep and hoping to win on penalities.
It looks that we watched different games. I kinda agree about Arsenal - Porto, but Atletico - Inter was great game to watch, none of teams didn't waited for penalties and wanted to win in regular time.
