Based on previous windows, we average out at £100 million net spend each summer.
This being a window of 'extraordinary circumstances', let's say that gets cut in half this time around.
We might take the attitude of why let the perfect be the enemy of the good, in which case we will sign a rotational midfield option for ~£35 million and maybe punt £15 million on a defensive equivalent of Dan James. Or we could end up saying that it's better to save our money and wait till next summer to spend, when the new financial realities are hopefully more clearly defined.
In any case, United fans like us will be disappointed, because we're not taking full advantage of the potential in this squad, which is higher than it has ever been since Fergie left. Whatever the reasoning behind it, we are very unlikely to improve on the squad that just about eked out a Champions League place.
