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

Alcaraz, threatening to dominate Wimbledon in much the same way as predecessors Bjorn Borg, Pete Sampras, Roger Federer and Djokovic, continues his title defence with an intriguing semi-final against big-serving Fritz.

"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.
