No I'm not saying that. I'm saying Lacazette intentionally stepped beneath Pogba. You want mental gymnastics? You're genuinely trying to tell me Lacazette had no idea someone was coming in behind him to challenge here. Not only that, you try to justify it by saying he thinks he's challenging Fred, when it's abundantly clear he steps away from Fred, and turns his back in a different direction. Sure...
The reason why Pogba doesn't a.) knee Lacazette in the back and b.) doesn't end up on top of Lacazette, back to back, is because Pogba is in control. It's not a reckless challenge. He's not jumping into Lacazette as Lacazette is with Pogba, which coincidentally is why Lacazette's fall is much harder. Lacazette clearly makes no attempt to ensure Maguire isn't hurt from his reckless challenge, but you want Maguire to ensure Lacazette isn't hurt? Neither challenge is great, but one is infinitely more understandable than the other. There's a reason why Maguire was awarded a freekick and Lacazette was not.
