I am happy to announce, that Messi's assist stat in the category '90 Minutes' in the season of 2015-16, has been his best to date.
Though he has one more game to play this season, his stat can not fall lower than 0.4954(=0.50), no matter the outcome of the Copa final.
Should he assist in the final, then he would only add to his own personal record.
What a player.
*EDIT
If the final goes into overtime and he doesn't assist his stat will fall to 0.4924(=0.49), meaning, that he would lose his record and instead tie his old record of 0.49 set in 2011-12 and 2014-15
