Barbora Strycova's coach gave a damning verdict on Jo Konta's performance in the Wimbledon
The British No 1 led 4-1 in the first set but her Czech opponent reeled her back in and Konta was left looking one-dimensional by the end.
'She didn't change anything,' said Strycova's coach Lukas Dlouhy. 'That's why she lost.
'Barbora has a lot of things in her pocket, she can do serve and volley, slices, everything.
'If you're playing against a player like Konta and she's more powerful than you then you have to find a way to eliminate that and play something different.'
Dlouhy will hope Strycova can be equally effective at discombobulating Serena Williams when they meet on Thursday afternoon.
The 23-time Grand Slam champion has built up a real head of steam this fortnight but Strycova will dip into her bag of tricks and try to pull a rabbit out of the hat.
'You can't say there are weaknesses in her game because she is the greatest player,' said Dlouhy, a two-time doubles major champion in his playing days. 'But hopefully we can find some.'
Strycova has made her first ever Grand Slam final at her 53rd attempt and the grass of Wimbledon suits her slicing-and-dicing style.
'I never saw a player more talented than Barbora with the touch for the ball,' said Dlouhy. 'That's why she's playing good on grass and why she loves this tournament.'
