I don't think that matters. It's still a foul, and he ended up endangering Digne's safety. That's a red card. Not all refs would call it, but I don't really have a lot of sympathy when it's something that can easily break a leg or shred a knee.
I call it a foul and a red card. I've had corches thank me for doing so. One team has three players with broken legs, in one season, caused by tackles like that one and the refs never called a foul.
