Under VAR, no way you see it and don't call it.

I see it the same. You can find arguments against a red, but at the end of the day, it's a clear 1 vs 1, relying on maybe he would've failed to control it or the ball is slightly behind him... doesn't beat the argument that Cubarsi is still by far the last man, and help is nowhere near.
