Boca Juniors are Manchester United’s first opponents in the Audi Cup which kicks off tomorrow evening Munich.

Sir Alex Ferguson has confessed that during sleepless nights in Manchester he has watched Boca Juniors playing on late night telly.

“If you can’t sleep at three in the morning in England, then you can see Boca,” said Ferguson. “And I don’t sleep at three so I have seen them many times. They are one of the best teams in South America. We had a very competitive game with them at Old Trafford three years ago.”
