I think Hughes is a decent manager, just not for us at this time. However, i think its pretty certain he will stay barring a ridiculous end to the season.
What did it for me was his total "eggs in one basket" approach to the transfer window in January. It was clearly obvious that we needed a frontman from September onwards last year, yet when the window opened we didnt have a plan B. We had a whole month to solve the problem, yet didnt. Yes we got Bellamy, but he's not the type of striker i'm talking about.
We're now stuck with limbering through to the end of the season with a mixture of Caceido, Evans and Sturridge, and I would guess at least 2 out if the 3 wont be at the club in the summer.
