Why some fans aren't happy with Roger Federer's epic train selfie

Roger Federer sent the tennis world into a frenzy with this epic selfie on the London tube, but a number of fans aren’t happy.

Federer, Novak Djokovic and the rest of the participants in the ATP Finals event shocked commuters on Sunday by taking public transport to the event’s official launch party.

Fans went absolutely nuts over the epic selfie, which contains about $800 million worth of tennis talent.

However there’s a very simple reason why a number of fans are upset by the photo, and that’s because Rafael Nadal isn’t in it.

The selfie contains fellow big names Kei Nishikori, Marin Cilic, Alexander Zverev, Dominic Thiem, Kevin Anderson and John Isner.

However Nadal is a notable omission after he withdrew from the event with injury.

Rafa’s fans felt that the photo wasn’t complete without the current World No.2.

A number of other punters also took a cheeky dig over the fact that the tennis stars were seated comfortably in the carriage while a bunch of regular commuters were forced to stand and looked visibly uncomfortable.

“Although we’ve probably all ridden on the tube a time or two, this was very different,” Isner said of the journey.

“It’s a very cool way to make an entrance.

“There were quite a few surprised looks on the faces of folks, especially when Roger and Novak walked by. It was a pretty cool treat for them.”

Why Nadal isn’t there

Nadal announced that an abdominal muscle problem, which prevented him from playing in the Paris Masters last week, and ankle surgery had forced him to pull out of the season-ending event.

“Unfortunately I had the abdominal problem in Paris last week and I also have an issue in the ankle joint that has to be removed in the operating room today,” the 17-times Grand Slam winner wrote on Twitter.

“This way I hope to be in full condition for next season.”
