I particularly remember when Lahyani was chair umpiring a match involving Jonathan Labella, some time in the mid 1990’s. Labella was not happy about the way he was playing and threw his racket countless times. Mohamed smiled through the whole thing. As he left the court, he walked up the stairs from the Center Court and saw Jonathan Labella’s father sitting there on one of the red comfortable chairs. Labella’s father had been swearing throughout the match and was very angry with the loss and said something about a few bad calls. With his unique voice, Mohamed responded: “Your kid could become a really good player, as long as he learns to control his emotions.”
A tough day in the career of Lahyani came at last year’s Paris Masters, when there was a long controversy about the number of challenges Andy Roddick had left in the final set against Jo-Wilfred Tsonga. Mohamed said that he was 100 percent sure that Roddick had another challenge, but the person in charge of the Challenge system argued for the contrary and didn’t want to award Roddick another chance. In the end, Roddick got the challenge. However, a look at the tape proved that it was in fact Mohamed who was wrong. Roddick had used all his challenges earlier during the set. Take a look below.
