I think their taking the long approach. Its selfish, but for them it makes sense. Ten Hag wasn't their signing and no one can blame them for his appointment and poor performances. At the end of last season, if they had sacked him, there would have been fans and large portions of the media reacting negatively to their decision. Despite it being really important to our current season to have him gone as soon as possible, for INEOS, buying time comes with low risk. They get the time and space to get what they want, how they want it, whilst also being on the right side of optics. I genuinely believe that this is why they actually kept him.
Noone can say that they didn't give him a chance, back him in the market or support him publicly, like people tried to do with Ole, Mourinho, Moyes and LVG. I think we're speaking with managers on the backend, but are making sure to put a public face of some support.
