Mohamed Lahyani is definitely one of the best and most charismatic chair umpires in tennis right now, but like everybody else he can commit some mistakes.

Steve Johnson was playing against Grigor Dimitrov; the American blasted a serve that Mohamed called out, but the Hawkeye clearly showed that he was incredibly wrong.
It also happens to the very best.
