Federer: SABR here to stay

Roger Federer has vowed to continue using his chip-and-charge "SABR" attack in the new season despite making changes to his coaching team in the off-season.

Shortened for "Sneak Attack by Roger", the world number three has used the tactic of rushing to the net on his opponent's second serve with aplomb during the 2015 season.

"I would love to keep trying it, now I have time to practise, so I am sure I will spend some time on that as well and see if it's something I should keep up," said the 34-year-old whilst in Singapore for the final leg of the 2015 International Premier Tennis League (IPTL).

"I am happy that it kind of worked, it was fun and it was all over the news, I thought it was quite exciting for me personally," he continued after crediting coach Severin Luthi for the tactic.

The Swiss ace goes into the 2016 ATP Tour season having made changes to his coaching team, with Croatian Ivan Ljubijic replacing Stegan Edberg. The Swede was only supposed to work as an assistant coach with Federer for 2014, but so successful was the partnership that he signed on for another year.

"I'll stay in touch with Stefan Edberg, he's been a wonderful guy, an incredible inspiration and motivation for me," said Federer.

"Unfortunately we won't be working together as much anymore but he said he would like to come around for some tournaments and we'll still be in touch."

Federer added that he hoped to return to the IPTL next year, having enjoyed this season's competition thoroughly.

The IPTL, which were also hosted in Japan, the Philippines, India and the UAE, is a team event using a shortened, sped-up version of the game.
