I don't think it is. Aguero had an off night, Silva was not as bad as what I read in the joke of a match day thread. I wouldn't say not being voted as motm in an away game in Europe is a sign that there's an elephant in the room or not.Noticing that so far Aguero & Silva have one vote between them.
That's the current 'elephant in the room' rather than the thread on Sterling imo.
It's not a secret that Silva has had a rough few months. It's certainly being discussed and not brushed under the carpet.
