He is already one of the highest paid around, isnt he?
There are a myriad of reasons I think it makes sense for him to stay. The key one for me is the leg work he has already done here.
His way takes time, its not instant impact, and he has his process 4 years in now and gearing up for more progression.
In doing so, he has also earned autonomy (as you say) and holds a great deal of clout at the club. Not something readily available with a move.
A lot will come down to just what potential he sees with us, IMO.
Impossible to argue Utd arent appealing, as much of a mess as they are, they are Utd. Its one of the biggest, richest clubs in the world, theres no way that wont catch someones eye.
Though I agree with you, I feel like there is more to Poch and his decisions than simple kudos.
