It does look like a bad move by united, but that is Van Gaal.. He is known as a stickler for things to be a certain way and we dont know what other reasons might be for change of venue other than travel time..
Maybe he feels the two hour travel back on a coach might be bad for us during pre season.. It is not an option during the season, but it is an option to be at our best when the season kicks off..
We did great last pre season, but had a dreadful start to the actual season, which affected our final league place.. Not saying we could have won the league, but a better start could have pushed for 3rd comfortably?!
So although, I agree it is bad for the fans who had planned this before hand and it sets them back financially, if it helps us start our season right, I am for it..
I read on telegraph that those fans who got their money refunded, get first option on these tickets at the new stadium.. As one of the posts above said, his mates could make the 4 hour round trip and still make the game.. It is not my place to say what they should do.. But cancellations happen..
