Cristiano Ronaldo confessed the trademark thunderbolt which gave Juventus a precious win at Empoli happened so quickly even he could not remember it.
The 33-year-old rifled a swerving shot into the top left corner to complete both his 16-minute double and Juve's recovery in the testing 2-1 victory.
His first was a coolly-taken penalty that cancelled out Francesco Caputo's classy 28th-minute opener as the champions relied on their star forward to temporarily move seven points clear in Serie A.
Ronaldo, who now boasts seven goals in just 10 league appearances, praised his team-mates' grit at the end of a week that included a 1-0 win over Manchester United in the Champions League.
