Lionel Messi became the player with most assist in La liga as far as statistics could go with his assist to Neymar in Barca's 5-0 win against Levante.

It is normal for a player to be the highest goal scorer in the history of a competitive League. However, it is very rare for that same player to still own the record for the most assists in the history of that same tournament. It is in fact, almost impossible.
Barcelona pin-sized wizard Lionel Messi is the top scorer in the history of La liga, beating Telmo Zarra's previous record of 252 goals. However, the Argentine seems to be far from contented with that accolade and reached another milestone after he provided the assist for Neymar's goal against Levante, becoming the player with the most assists in La liga history (as far as stats could go) with a total of 107 assists. Wow!
Few months ago, the Barcelona number 10 became the top scorer in La liga history and now his name is registered as the player with the most assist.
