Not backing him after we've given cash to the likes of Silva, Allardyce and Koeman would be a new low for this club. I doubt he would of taken the job without some serious financial promises.
Ancelotti needs to be given full control of who he's bringing in and who he wants out. Brands should be acting as negotiator rather than identifying the players. We've been given a genuine chance to achieve something here, for once the chips have fell in our favour and we've ended up with an actual winner at the helm.
