Gerard Pique:
The Dutch manager came to the limelight as a manager at the Camp Nou as he took the Catalan outfit to some memorable victories. He helped an influx of young talent to the senior side and was one of the most effective managers in Spain at that time. However, he was not exactly a saint as one Gerard Pique learnt when he was quite young. The Spanish defender is among the best in the business at the moment but when he was 14, Louis van Gaal, who met him in training was a bit too harsh. He pushed Pique onto the ground to prove that he was too weak for a defender. Van Gaal said Pique will never become a top class defender but surely, the jokes on him.
