None of that follows. It's your spin on the situation, whereas the likelihood is that there are legal discussions between UEFA and Sakho's legal team.
I'm sure there are. Because UEFA screwed up. If they had their ducks in a row, there wouldn't be any need for discussions or negotiation or whatever wrangling is taking place.
As for it being "spin", all I can say is I'm well educated in organizational behavior as well as behavioral science in general.
UEFA is not acting at all as an organization with the courage of its conviction. They're acting quite like an organization in a pickle and trying to deal with their quandary.
The Sharapova case was different totally. She admitted she took the substance, just didn't know it was banned even though it was on the list. She was provisionally banned (wasn't allowed to expire) and then very expectedly given a ban.
Here Sakho was suspended then now he's not but he effectively still is under sanction because the case hasn't been resolved yet, which means UEFA isn't able to resolve it because they've messed something up. So they're hedging by allowing the ban to expire but not clearing him.
