Arsenal boss Wenger: I didn't want to sell Henry
Henry joined the Spanish giants for £16million last month after eight years with the Gunners and Wenger admits it was firmly the player's decision.
"Of course you don't want to lose a world-class player without having thought about it," he told the News of the World. "At the end of the day, it was his decision.
"He wanted to leave. You don't make a decision like that in a minute. You check to see if the player is really completely sure of what he wants to do.
"But Thierry Henry's decision is down to him. It's not my decision. He wanted to make the move.
"He's nearly 30. Maybe he didn't have the patience anymore to let the young team develop. You can understand that. It was a tough decision."
