Alex Ferguson visited London to see how Arsene Wenger coaches his team. After one day he is not really impressed by the training practices, so he asks Wenger how he gets his players so sharp. 'Well it is simple. I sometimes ask my players a difficult question, and that way they stay really sharp mentally'. Wenger asks Henry to come over and asks: 'Thierry, he is not your brother, but still he is your father's son. Who is he?' 'That is not difficult', Henry answers immediately, 'Of course that is me'. 'You see? That's the way you keep them sharp', Wenger says to Fergie. Ferguson decides to try this the next day. He calls Wayne Rooney over: 'Wayne, I have a question for you', he says, 'He is not your brother, but still he is your father's son, who is he?' 'My God, Coach', is the striker's reply, 'That is a tough one to answer, can I answer tomorrow?' Fergie agrees. So that night Rooney decides to call Ryan Giggs. 'Ryan, maybe you know the answer to this question, he is not your brother, but still he is your father's son. Who is he?' 'That is easy, that is me!', says Ryan Giggs. So the next day Rooney walks full of confidence to Ferguson. Fergie asks: 'Wayne, do you know the answer to my question now?'. 'Yes it was actually very easy', he says, 'It is Ryan Giggs!' Ferguson answers: 'No of course not, you stupid idiot. It's Thierry Henry.'
