No, he never said that. He said they have a great time in the U.S., the training is superb, the players enjoy it, etc. We've had U.S. pre-seasons and started seasons well before - 2004/2005, 2006/2007 and 2007/2008, all examples of this.
He changed it this year for the sake of change, because hes desperate for a good start to a season for once, and he's running out of ways to try to change pre-season without addressing the real problem - selling a top player and not replacing him and/or doing transfer deals after the season has started and thus disrupting the team.
