After having looked at the first goal, I think blame can be put on other players as well:
Busquets pass is maybe too harsh (don't really think so though, think he might've looked for Alba as well)
Then Griezmann could either let the ball pass in the first situation
Either way he isn't helping quite enough afterwards
Neither does Pedri. Both players should see the two opponents approaching Umtiti and offer the easy pass inbetween, instantly.
Busquets shouldn't then let the ball pass through him, but he is pretty close, and it is hard to react.
Mats and Araujo should maybe not let the ball pass between them - Araujo one step back (MATS one step forward maybe?)
Roberto should be one or two steps closer from the beginning.
Second goal is a very stupid pass from Griezmann, but shouldn't lead to a goal. Perfect pass and run it seems, and a misjudgement from Umtiti. But Griezmanns pass is more annoying.
