I can take it at this early stage but if he is still blaming the team in a few months then he has to look at himself for not being able to get them performing better and listening to what he is trying to get them to do.
If they are ignoring him and doing their own thing then the problem lies with him as this is what he is ultimately paid to do.
I'm not sure how he can guarantee it won't happen again under him if he is laying the blame firmly at the feet of players who he is hinting are making mistakes and playing how they like.
