Beginning of the end and kickstart to new beginning?

DOES this classic smash-and-grab result really signal lift-off for Louis Van Gaal at Manchester United and the end of Arsene Wenger at Arsenal?

Was the Dutchman proved to be a dynamic tactical genius against a worn out Frenchman who has become a footballing fool? Those were the sort of questions being knocked about by both sets of supporters after this fairly remarkable match in north London.

The answers are not so obvious, however, as Arsenal were by far the better side for so much of this match, succumbing again to poor finishing and defensive naivety.
