Bruce given until end of season to prove himsel

[Jammy89]

It's just a nice way of saying, "You'll be replaced in the summer (whenever the pre season is this year)!"

Exactly.

Plus they can't say anything else.

But he and everybody else knows, he's gone once the season ends.

I assume it also means they can get who they want lined up rather that doing it though the prism of "Newcastle need a manager".
