Barcelona are definitely the giants in Spanish Supercup with most titles (13), most entries (23), most matches won (20) and most goals (73).
After winning 2-1 over Seville in Tangier on August 2018, Barça have increased their hegemony in the Spanish Supercup to 13 titles (1983, 1991, 1992, 1994, 1996, 2005, 2006, 2009, 2010, 2011, 2013, 2016 and 2018), becoming the best club in this competition ahead of Real Madrid, which have raised the trophy 10 times (1988, 1989, 1990, 1993, 1997, 2001, 2003, 2008, 2012 and 2017).
Of course, Madrid won the one in 1989 without playing the game because they were both winners of the League and Cup at the same time.
Since first played in 1982, the Spanish Supercup has always been a bluish tint. With 23 entries, Barcelona have played the most matches - 45. Also, they have won the most games (23) and scored the most goals (73).
In addition, Messi is the player with the most entries in the Super Cup. He has intervened in 11 editions (2005, 2006, 2009, 2010, 2011, 2012, 2013, 2015, 2016, 2017, 2018), playing 18 matches. He is also the player with most titles (2005, 2006, 2009, 2010, 2011, 2013, 2016, 2018), scoring in seven different editions, more than any other footballer in the history of the Spanish Super Cup.
And if it wasn't enough, Messi scored in four successive editions (2009, 2010, 2011 and 2012), a unique performance in the history of the competition. A long and lustrous history that can expand even further.
