( CNN ) -- World number one Novak Djokovic eased any concerns over his ankle injury with a comprehensive win over Albert Montanes as the Serb eyes his third title at the Italian Open . The 2008 and 2011 champion twisted his right ankle in a Davis Cup match last month before appearing to damage it again in last week 's Madrid Open defeat to Grigor Dimitrov . At Foro Italico however , Djokovic needed just 70 minutes to rally from an early break to beat qualifier Montanes 6-2 6-3 . The six-time grand slam winner says the display is a step on the road to performing at this month 's French Open as well as at Wimbledon in June . `` It was a good performance , even though I know I can do better , '' Djokovic , who has reached the Rome final four times in the last five years , told reporters . `` I know my game has to be better in order to win my next challenge . But I 'm heading in a good way because I did n't have a great week in Madrid and did n't have much practice . `` I came here very early ; from Wednesday I spent a lot of hours on the court working hard , trying to prepare myself for what 's coming up this week and also after the tournament in Rome -- two Grand Slams in less than a month 's time . `` It 's a very important period for all of us and I need to be physically , mentally , fresh and fit and I think I 'm on the right way to be like that . '' The French Open gets underway in Paris on May 26 and finishes on June 9 , just over a fortnight before the start of the Wimbledon championships . Federer , whose return to action in Madrid after a two-month break ended with a third-round loss to Japan 's Kei Nishikori , also eased through to the third round after beating Italian wild card Potito Starace 6-1 6-2 . Meanwhile , Serena Williams gained some family revenge when beating Laura Robson , who knocked sister Venus out in the first round , in straight sets . The world number one 's comfortable day against the rising Briton was in stark contrast to many of her seeded colleagues , three of whom crashed out on Tuesday . Poland 's fourth seed Agnieszka Radwanska was the highest to fall , losing 6-7 6-1 6-2 to Simona Halep of Romania in the second round , but she may have gained some consolation by seeing sister Urszula inflict defeat on 15th seed Ana Ivanovic . Tenth seed Caroline Wozniacki of Denmark also failed in her bid to reach the second round , as the former world number one let slip a 5-2 lead against 48th-ranked Bojana Jovanovski in a third set tiebreak . The girlfriend of golfer Rory McIlroy has struggled on clay this season , exiting in the first round in both Spain and Germany over the last month , and now succumbing at the first hurdle once again . Jovanovski , 21 , ended a poor run of form as the Serb claimed her first victory since the Australian Open in January . 2011 Wimbledon winner Petra Kvitova became the first woman into the third round as she beat Germany 's Sabine Lisicki in another match that went to three sets .
