Tbh I wouldn't have hired Ole in the first place, but I don't think you can sack him before even giving him any chance to shape the squad himself. It would show a total lack of forward thinking at all if we sack him before the summer, and would really worry you over what direction we're going if that doesn't already worry you anyway.
The real thing that's changed is you can lose games, and our recent record is dreadful, but in the early weeks we looked full of creativity, now there is zero creativity in these games, and that's why we're not scoring goals, because we are a lot of the time creating absolutely zero, especially vs better teams where we simply seemed to have no idea. The one exception on paper for that was PSG, but even then they gifted us 3 goals, outside of that we didn't really look like scoring there either.
This is a huge job now, and it's going to take more than 1 window to get us anywhere near where we want to be. Our squad is probably about on par with the Liverpool squad that Klopp inherited, and it took him like 2 years to get them anywhere near where he wanted to be, and they still haven't actually converted that into anything yet. Man Utd will have more money than Liverpool, but at same time does anyone really trust us to use it well, we have have wasted a frightening amount of money, we're not even heading in the right direction yet, and it's anyone's guess at this point if Ole really is good enough.
