Depends first of all what you mean by want to stay, do you mean want him to stay until the end of his current contract rather than being sacked this summer?. Probably true. But long term no I don't think there is any particular enthusiasm for that.

And again the opinion is nuanced and varied, between those who want him gone now, those who want next season to be his last regardless of results, those who want him gone if we don't do significantly better than last season and those in the very small minority who want him to stay as long as he wants no matter what.

I think the fan base is far more anti Wenger than it ever has been, and is generally frustrated with him but I think the desire for him not to be sacked is based more on sentiment than anything. I think they want him to go, but they want him to make that decision himself.
And as discussed earlier if he fails as badly as he did last summer the atmosphere will become poisonous enough for him to walk.

In hindsight the expectation that he might have gone at the end of season just gone was probably fanciful although I can blame no one (including myself) for desiring it.
