"I can't see any downside to this to be honest," Gallagher said. "Going from a cult football club that black cab drivers in London all like and patronise you [about], to being the richest club in the world is just staggering.
"I always kind of knew that 40 years of loyalty would be repaid somehow and I always knew that a day would come when we stagger everyone in football. It'll be nice to know that every gallon of petrol a Manchester United fan buys is going into our transfer kitty."
Gallagher, who is currently with his band in Canada, said that he discovered the news after a flurry of text messages.
"We're on tour in Winnipeg and I woke up to find I had 19 text messages. Now that usually means I have either offended someone in an interview, or something bad has happened at home.
"But they were telling me to put on the news, because we've been bought by some Arab prince," he said. "I was laughing at first, and I still really can't believe it.
"Then to top it all off just before we went on stage I found out we've signed Robinho. I mean it's staggering, just unbelievable."
