Absolutely no doubt about that IMO. Some have always claimed we need much better/more signings, but a lot of this negativity simply wasn't there before that game.
Think people were content to wait for signings in the days before Arsenal, especially since KK said he wants 3 or 4 new signings and we would get them. Granted we have got 2, but they arnt well know, or big names so to speak, which itself has annoyed people. Maybe 2 more household names would have changed the face of things
