The window isn't over, clearly things are going on behind the scenes. I expect players to come in as do most fans. There is no reason why that wont happen.
A comment of "watch this space" means just that - the club are doing things, trying to make things happen and want to progress. It doesnt mean that there are umpteen superstar players imminent or signing in the next week. If people misunderstand what's said and want to read more into it then they're evidently going to be dissapointed.
I personally prefer an honest and positive comment like that, to what we're used to - i.e. "there's no value, we've got a good squad" etc. At the end of the day, the club will be judged on where we are at the end of the transfer window for me. The noises that have been made have been positive, I like the fact that the business is not being done out in the open under press scrutiny and I'll from an opinion when the dust settles and not before.
As I;ve said before, years ago, people would have waited until the end of the summer to see where we were, now people seem to expect in depth comment from the club about every twist and turn, and updates on which players they want. Clearly these things take time and I have no issue with the club not rushing into buying players. Im happy to trust Van Gaal to get the right players and get the right results.
