( CNN ) -- Juventus took an important step towards retaining the Serie A title with a battling 1-1 draw at the Stadio San Paolo of nearest rivals Napoli Friday . Negotiating the testing away fixture with honors even left Juve six points clear of Napoli at the top with just 11 games remaining . The league leaders had to put an ugly pre-match incident behind them , with Italian news agency ANSA reporting that a window in their team bus was broken by a missile as they traveled to the ground . Nobody was injured in acts described on Italy 's Sky TV by Juve general director Guiseppe Marotta as `` deplorable and with little to do with sport . '' The game itself started at a frantic pace with the visitors taking the lead after just 10 minutes as Giorgio Chiellini headed home . He had been recalled to the starting line-up and connected with an Andrea Pirlo left wing cross to score . Juve might have added to their advantage while Napoli 's leading scorer Edinson Cavani continued his lean spell -- failing to net in his last seven matches . However , Napoli did level just before the break as Gokhan Inler 's fierce shot deflected past Gianluigi Buffon . The visiting keeper had to save smartly from Marek Hamsik at the start of the second half as Napoli pushed for the winner . Another Hamsik effort was parried out to Blerim Dzemaili , but the Swiss international wasted the chance . There was still time for Inler to test Buffon again , but Juventus hang on for a valuable draw . Antonio Conte 's men will now look to secure their place in the quarterfinals of the Champions League , entertaining Scotland 's Celtic in midweek and leading 3-1 from the first leg . But Conte played down premature talk of the Italian championship being wrapped up . `` The title is far away , we are six points in front which is a good advantage . `` But there are another 33 available and do n't forget we still have to play Milan , Inter and Catania , '' he told AFP .
