Federer, who turned 40 a week ago, has previously said he still enjoys life on the tour but there are fears his body may cause him to retire before he wants to.

The ATP 500 event in Basel has often been many people’s prediction for the tournament he will want to say goodbye at, being the tournament he was once a ball boy at which is also held in his home city.

With the 2021 edition already cancelled due to uncertainties during the pandemic, if the ten-time Basel champion wants to retire at his home event he will have to wait until the end of next year.

As retirement rumours remain rife, many experts have given their opinion on the end of Federer’s career, including one of his former fitness trainers.
