Borna Coric believes former world number one Roger Federer has a chance of triumphing at both the Australian Open and Wimbledon next season.

Federer successfully defended his Aussie Open crown in January this year – his sixth title at Melbourne Park – and took his Grand Slam tally to an incredible 20, three more than Rafael Nadal, who is second in the all-time list.

The Swiss was fancied to win his ninth trophy at the All England Club in the summer but suffered a shock quarter-final exit at the hands of South African Kevin Anderson, who lost to Serbian star Novak Djokovic in the final.

Attention is now turning towards the 2019 campaign and 37-year-old Federer, who lost in the semi-finals of the ATP Tour Finals for the second straight year, has been backed to enjoy more success by Coric.

The Croatian, who turned professional in 2013, believes there is a good chance the Swiss can add Grand Slam 21 to his CV. “I think it’s possible,” Coric said when asked by Sky Sports Italy about Federer’s chances.

“I faced him a couple of times this year. Roger takes a break during the clay-court season and it gives him the possibility to rest. “Seeing him at the age of 36 was fantastic, he played five sets also and it was something special.

So I definitely see him in the race to win a Grand Slam, obviously one of his favorite tournaments is Wimbledon, so he may win there.”

Federer is 7.50 to win the 2019 Australian Open and is priced at 4.00 to strike at SW19 again.
