Sverin Luthi, the coach of Swiss legend Roger Federer, believes that the 37-year-old has made the right decision in pulling out of the Rogers Cup, as he looks to win his sixth US Open at the end of the month.

The 20-time Grand Slam champion was due to return to play at the Rogers Cup in Montreal, however, the Swiss star decided to withdraw, with ‘scheduling’ his main reason for pulling out.

The world number two is now preparing to play at the final Grand Slam of the season, the US Open at Flushing Meadows later this month.

Many have questioned Federer’s decisions to pull out of several tournaments in recent months, including world number one and long term rival Rafael Nadal, however, coach Luthi has backed Federer’s choice to skip certain competitions ahead of Grand Slams.

Would it be an advantage for him to play two tournaments prior to the US Open? For me, nope.

But the most important thing is that he is fresh, motivated and inspired.

At 37 and with his experience, he doesn’t need 25 tournaments before a Major. I don’t think it would be an advantage to play Toronto and Cincinnati.
