Roger Federer tips surprise underdog to challenge Nadal and Djokovic

Twenty-time Grand Slam winner Roger Federer has tipped Denis Shapovalov to go far at the Australian Open. Federer reckons Shapovalov could have a strong showing. “Both guys [Nadal and Djokovic] when they are injury-free they are always tough to beat,” he said. “I think the win from Tsitsipas at the World Tour finals [in November] was a big one. That was a huge step forward after he beat me here [at the Australian Open] last year. “He had a great run here. Medvedev has obviously had a great run. Shapovalov is a very exciting player as well.” Source- Express
