No, he was tested after the wedding so the assumption, I and everyone else is making, is that he caught it at the wedding.
I didn't know how to word it but I was trying to say, if your average Joe rings his boss and tells him he has COVID after attending a wedding then fine. If a video then surfaces of that member of staff not wearing a face mask and ignoring COVID guidelines, I'm 100% sure that member of staff would face disciplinary action for missing work.
I'm pretty sure Klopp would've allowed him to attend the wedding, I'm also sure he would've reminded him to wear a mask or expected him to do so. At the very least, there's now going to be a trust issue between them.
