Dudi Sela insists he can break into the world's top 50 – despite crashing out of the Australian Open in the first round.
The Israeli number one was beaten in straight sets by Argentina's Juan Martin Del Potro after failing to convert a set point in the opener.
But Sela says his level of performance against the former US Open champion has given him plenty of optimism for the year ahead.
"I hope I can break into the top 50 but it's not easy because there are a lot of good players," said Sela.
