Carlos Alcaraz and Taylor Fritz will face each other in the Wimbledon semi-final, but it won't be the first time the duo have been in the headlines together

"There are always small details that can be improved," said his coach Juan Carlos Ferrero on the eve of the semifinal between Alcaraz and Fritz. "I won't reveal what these details are because I don't want to give any advantage to his opponents, but we are working to make some small adjustments to his game," he added.

It's a tall order to say the least, but Fritz has a chance to be the first American man to make the Wimbledon final since 2009.
