"You don't want to be in the position where players want to go somewhere else, even if it is a great club like Barcelona," Henry said.
"It's hard to understand why players would want to go to a league where the competition is so weak. They must play 30 or so meaningless matches per year waiting for Champions League matches."

"They'll be watching this weekend and could have been playing," Henry said. "But (part owner) Mike Gordon, (sporting director) Michael Edwards and everyone in our scouting department have done a terrific job in making the best of those two difficult situations."
