Roger Federer says he's excited to make a return to tennis for what will be only his third match in 15 months in Geneva.
Federer has had a long lay-off from the sport due to double knee surgery and subsequent recovery time needed. He briefly returned in February to play two matches in Doha but later admitted it was more of a test to see how his fitness was going.
He will now make a full return at the Geneva Open, in his home country, before going straight on to Roland Garros before Wimbledon.
Speaking ahead of his first match on Tuesday, Federer says although he's happy to return, he needs to focus on his own game and not be too concerned with comparing himself to others.
"I need to do my thing, I need to play 10 matches to give you a better answer [on my level]," said Federer.
"Of course there are question marks around my level right now. We will find out a little bit more tomorrow [Tuesday].
"In practice, things have been going well, so I'm happy there, and when you come back from an injury, you are in a different place to everybody else.
"The players are there, I'm here at the moment.
"I'm excited about the comeback; that's what my focus needs to be on and not trying to be the same level as Rafa and Novak right now."
Federer who will turn 40 this year, currently holds the joint record for the most singles Grand Slam titles with Rafael Nadal, but suggested he might have to be even better than he was before in order to be competitive.
"The generation of [Stefanos] Tsitsipas, [Alexander] Zverev, [Andrey] Rublev and [Daniil] Medvedev have all again gotten better naturally, because they have more experience," said Federer.
"Dominic [Thiem] won a slam in the meantime, Rafa and Novak are still where they are.
"So, you would think that the game has improved again. For me, that's going to be an extra challenge, extra hard to find that level.
"But one I knew from the get-go that would never be simple, regardless if I was going to be out for three months or now almost a year and a half."
Federer's first match will be against Spanish Pablo Andujar on Tuesday in Geneva.
