20-time Grand Slam champion Roger Federer has admitted that ‘it would be a joke’ if he was to aim to return to the top of world tennis, Sky Sports report.

Federer is currently ranked fifth in the world heading into the Miami Open final against American John Isner on Sunday.

The 37-year-old recently claimed his 100th career singles title at the Dubai Tennis Championships, becoming the second male to reach that landmark.

The Swiss star, who will reportedly continue his professional career in 2020, is currently nine away from equalling Jimmy Connors’ all-time record of 109 singles titles.

And asked if returning to the top of the world rankings was his ultimate goal, Federer admitted that winning tournaments is his current aim.

I think it’s not reasonable to think that way at 37.

I think it was one of the favourite moments in my life last year in Rotterdam when I was able to get back to world number one at 36, having won the Australian Open and Wimbledon in the same year, and winning the Sunshine Double and all that stuff, it just aligned itself beautifully.

Novak (Djokovic) has just won three (Grand) Slams, so I think it would be a bit of a joke if I said that was my goal.

The veteran then went on top heap praise on former world number one Andy Murray and Spaniard Rafael Nadal, who are both currently out injured, revealing that the tour is a better place with the duo around.

It’s definitely a better tour with them. Regardless of their injuries they will come back and I hope when they do come back they are going to be very strong, like the last few times, with Andy in particular, with the uncertainty about his hip, I just wish him the best.
