Roger Federer looked to be moving like his old self as he took to the practice court in Doha on Saturday.
The 20-time Grand Slam winner is returning to action for the first time in over a year following double knee-surgery at the tournament, which gets underway on Monday.
He is also expected to play Dubai the following week before taking a training break to assess how his knee has stood up to its first tennis in a year before resuming his comeback during the clay season.
Federer, though, appeared to be in very good shape in practice.
Federer has a bye into the second round for Doha, where he will face either Dan Evans, who he practiced with on Saturday, or Jeremy Chardy.
Should he come through that, either Borna Coric of John Millman likely await before potential semi-final clash with Denis Shapovalov.
The top half of the draw looks much stronger, though, where top seed Dominic Thiem may have to negotiate a path past Roberto Bautista Agut then either Andrey Rublev or Stan Wawrinka to earn a place in the final.
