Lionel Messi has now scored the most goals in a single European season after netting the second goal in Barcelona's 4-0 victory over Espanyol on Saturday.
The prolific No.10 broke Dudu Georgescu's of 47 goals for Dinamo Bucharest in the 1976-77 campaign when he doubled his and the Blaugrana's tally during the Catalan derby at Camp Nou.
Messi is now on 50 for the season, having followed up his pair of strikes with a further two more and securing his eighth hat-trick of the campaign in the process.
The record is just one of several in what has been a memorable season for the Argentine, beginning with his five goals against Leverkusen in the Champions League to earn him the distinction of being the competition's first player to score five in a single match.
Messi also became Barca's all-time top goalscorer and the highest scorer in one Spanish season, while in the past week, his treble against Malaga meant he broke Gerd Muller's long-standing 67-goal haul in one campaign.
