Obviously he will keep playing "shit" (in your words) because our style demands the opposition to defend with 3/4 of their squad in the box. Griezmann is not a great dribbler, but he has the predator skills inside the box to score a lot of goals. As I said previously he needs to get serious and try to score boring, tap-in style of goals more instead of complicating things. I can feel his love for football, he enjoys playing for Barcelona and it will only get better with time, he is a class player.
As for Luis Suarez having the season of his life - well, nobody defends with 8 people in the box against Atletico Madrid. And who better experienced against such a wall than him? Messi? Don't think so. "Park the bus" tactic was invented because of players like Messi.
I guess it's good that he played a bit more simple, as every time he tried to do something a bit more creative he lost possession in a more or less embarrassing way.
I also think he plays without timing when he plays simply as well (many times it takes some work to get the ball all the way to him, only for him to get the ball back to Alba without even thinking). He should use the time and space he gets better, and then play it simple.
The goal situations are what I expected of him when he arrived, why I was positive to him when he arrived. He has made some good runs in the box lately and he does have good technique.
I think he is the one underperforming the most in current Barcelona, despite the goals+assists, but he could play a role in my team, as a combined fox in the box and pressing forward.
I don't think he was good apart from the goals yesterday. The goals are obviously a given, and as an attacker when you summarize, he could be said to have had a good game. But I think he generally needs to do less in the midfield (this was better yesterday), lose the ball less, and still be a bit more threatening and well timed with the ball.
