Hardly surprising the press aren't cecking the facts. Why start now?
The fact that Lalas thinks Adu 'can't adapt to anything', if true, would relly rule him out of the Premiership. Good players have come here and failed to adapt, despite being extremely skillful (Veron being a good example, or Shevchenko for the time being, although he'd probably have scored more if he was at United), so maybe Adu would look ordinary here, but excel in Spain.
Still, I think you're right about the spin: THey want it to look like he chose to reject the Premiership, rather than have been rejected by United.
