Cristiano Ronaldo has written himself into the history books once again after the Juventus striker became the first player to score 50 goals in the Premier League, la- liga and serial A. The Portuguese's second-half penalty finish against lazio saw him clock up a half-century of goals in the Italian top-flight since his arrival in Turin, in addition becoming the fastest player to do so since 1995. In addition, the 35-year-old's converted spot-kick means that he has also equalled Giuseppe Signori's 1994-95 record for penalty goals in a season, with 12 successful conversions from inside the area.
