#2 Most El Clasico appearances - 44
Messi is currently six appearances (38) behind Real Madrid's Manuel Sanchís, who has 43 appearances in the fiercely-contested El Clasico derby between Real Madrid and Barcelona.
Messi and Barcelona are set to play against each other at least twice - two games in La Liga - but the two could face off twice in the Champions League and Copa del Rey, too.
The Barcelona player with the most appearances in El Clasicos is Xavi, who appeared in 42 matches.
