In Benfica's case, the coach needs to give these players a dressing down. We've certainly seen some of them behaving selfishly in several plays, which could have resulted in better outcomes.
But they were also unlucky, because they rebounded 3 or 4 times and the ball hit the posts/crossbar. Either approach could have done more, without a doubt.
In Porto's case, a team like Porto winning the game with two goals scored from penalties against Alverca doesn't demonstrate that much quality. In the end, what we saw was three teams with performances that were a little below expectations, but one of them had more luck, so to speak. Either way, it's part of the game.
The dressing down should be channeled into fixing how they defend together and the defenders in total. That was the opening game of the season and one can see that if they the backline is not secure and able to defend themselves when taking the lead, they're good as dead. The way they conceded those two goals disturbing for a big club like them. I mean through a corner and also a set piece kinda goal.
Above all, they played good football yesterday, but good football without a proper defence is like shit.
I can agree to these self-centered shots, when they should have passed the ball for the teammate in a better position for goal. I expect changes and upgrades ahead of the next game and if they fail to do that, they will see themselves conceding goals.
No words about Porto, I honestly didn't see their game.
