Translating and explaining xG context

I’m considering how to provide an English translation while also offering context about expected goals (xG) and comparing it to season averages, even though specific stats are unclear. A concise clarifying question could work well here, offering options like translation or a data background. For example, I might say, "Bayern generated just 0.65 xG away to Arsenal—their lowest of the season." I’d also be open to asking if they want more data or specific details like the match date.
