Clearly all options have risks, especially if the dismissal is carried out at the beginning of the season, and it is not certain that the new manager will be able to do his job better. Jim Ratcliffe certainly does not want to see the Red Devils sink to the bottom of the standings, because there are quite a lot of things at stake. Ten Hag has actually received full support in terms of budget, he managed to recruit five new players in the transfer window yesterday, but the adaptation period and player injuries are factors that hinder them from achieving consistency.
He may not be sacked based on what you said but he really need to improve in his managerial function to escape dismissal which seems like sack too, owner of club don't like excuses especially when the feel that they have don their own part and left for you as the manager to do yours, though they have just played 3 matches so far with 1 win and 2 loss which is not a good one for a team like Manchester United, this is the time for Erik Ten hag to restrategize for his team get back on their fit, as it stands the team owners can never be happy seeing their team in shamble, the fans are not even happy with the situation on ground, so i think a lot of work needs to be done, his choice changes are not nice sometimes this is really the part thats very bad.
At this point I expected Manchester United to withstand every kind of pressure to atleast get a draw from liverpool but they failed, with all the support he got from the owner nothing to show for it, as a matter of concern, he really have to up his games to get the result that's expected from him if not the club owner will have no option than to initiate the availabke option at his disposal.
