Jose Mourinho pays a visit to Arsenal, to see if he can pick up any tips on continental training methods. He asks Arsene Wenger how he keeps the players mentally sharp.
"Simple," says Arsene. "I ask them riddles. Let me show you." Just then, Theo Walcot is walking by.
"Theo, I have a question for you," says Arsene. "He is not your brother, but he is your father's son. Who is he?"
"That is easy," says Theo. "It is me."

Mourinho goes back to Chelsea and the next day at training he calls John Terry over. "John, I have a question for you. He is not your brother, but he is your father's son. Who is he?"
"Bleedin' ell, boss, I dunno. Why are you asking me?
"Mourinho explains that it's continental coaching, and gives Terry a couple of hours to think about it.

John Terry decides to go and talk to Cesc Fabregas, since he knows about these continental coaching methods. "Cesc, do you know the answer to this? He is not your brother, but he is your father's son. Who is he?"
"That's easy John. It's me."

John Terry goes back to see Mourinho, full of confidence.
"I know the answer now, boss."
"Go on then, son. He is not your brother, but he is your father's son. Who is he?"
"It's Cesc Fabregas!"

Mourinho rolls his eyes skywards. "No, you idiot! It's Theo Walcot!"

Hahahhaahhaahhahaahhaahahahah! U really got me there!
