John Millman may get the chance to cap his career-best season with a second shock win over Roger Federer in eight weeks, this time on the all-time great's home court.
At age 29, Millman is enjoying his best world ranking at No.33, having captured worldwide attention by ousting Federer in the US Open fourth round early last month.
Now the Australian is drawn to meet the winner of 20 grand slam singles titles again in the second round of the Swiss Indoor tournament in Basel this week.
That would be some feat, with Millman making his Swiss Indoors debut while Federer is chasing a ninth title, having made the final in his past 11 appearances at an event where he was once a ball boy.
First Millman must get past Germany's Jan-Lennard Struff while Federer has to overcome Filip Krajinovic.
Fellow Australian Matt Ebden will eager to continue his recent good form as he meets a qualifier in the opening round before a potential second round clash with German ace Alexander Zverev.
