If that's what you think is right then aye, you're bang on. Norwich took a week to appoint a manager, we're currently at 6 days, and the guy we want is in Holland with his assistant still employed in China.
Charlton was a midfielder and played when there were far fewer international games. Kane will be top scorer in no time right enough, which is some achievement considering the time and players that went between Charlton and Rooney.
Leaving us 4 points clear with a mostly fit squad, and plenty of the season to play for. Other than at the end of the season it's about as good it gets. Any new manager coming in should be happy with what he's getting.
De Boer has been sacked by inter and palace after less than 3 months at both, and went on to manage Atlanta United. I doubt his CV is at any risk managing us.
