Roger Federer has beaten Filip Krajinovic, Jan-Lennard Struff and Gilles Simon this week to reach the semi-finals.
But victories over Simon and Krajinovic were far from comfortable, needing a third and deciding set to get through both times.
Federer faces his toughest test yet against Daniil Medvedev this afternoon as he seeks his first ATP Tour title since the Stuttgart Open in June.
Federer suffered a shock defeat to Borna Coric earlier this month in the Shanghai Masters final.
And the 37-year-old has admitted he is still yet to rediscover his best tennis and knows a vast improvement is needed if he is to win at his home tournament.
“Of course my goal here is to win the tournament,” Federer said.
“On the other hand I know if I play like this I will have to fight much more to achieve it.
“It won’t just be presented to me as a gift.”
Federer has won nine ATP titles in his hometown of Basel and is arguably the greatest sportsman Switzerland have ever produced.
However, the 20-time Grand Slam champion admits the pressure of performing at the highest level has sometimes left him feeling “uncomfortable”.
“Wherever I go, I get welcomed with the word ‘From Switzerland’,” he said.
“So you automatically start to represent the country. I always liked it.
“At the same time, I was a little bit uncomfortable in this role.
“In the end, I am just a tennis player.”
