The Catalans have scored 167 goals in all competitions this term - 15 more than in the whole of last season. Barca's current unbeaten streak of 54 at home in all competitions is the second longest in club history. The club record is 73 and dates back to 1973-76. Lionel Messi has scored 29 goals in his last 16 appearances for club and country. Real Madrid is on an 18-match unbeaten run in La Liga (W15, D3). Its last league defeat came on Dec. 10, when it lost 3-1 to Barcelona. Los Merengues are yet to register a Liga victory over their arch rival since Pep Guardiola became Barca coach in 2008 (D1, L6). In 14 games against Guardiola's side in all competitions, Madrid's record is W1, D4, L9, with the solitary victory coming in last season's Copa del Rey final. If it scores on Saturday, Madrid will surpass its own record of 107 goals netted in a single La Liga campaign set under John Toshack in 1989-90.
