In-form Paris Saint-Germain attacker Di Maria was linked with a sensational move to La Liga giants Barca at the start of the season following the arrival of Neymar and Kylian Mbappe.
The 29-year-old found game time hard to come by, though he has since worked his way into Unai Emery's starting XI, scoring four goals in as many games, including a hat-trick against Sochaux in the Coupe de France last 16.
Reflecting on his failed transfer, Di Maria told TyC Sports: "I was really close to joining Barcelona but in the end, it wasn't to be.
"I started 2018 on a good foot, though, and I am really happy. I like assisting goals more than scoring them."
A controversial switch to Camp Nou would have seen Di Maria link up with compatriot Messi at club level.
"Messi is always the best, he's the best every year. Cristiano Ronaldo's a special player, but Messi's from another planet," said Di Maria, who will come up against Ronaldo and Champions League holders Madrid in the last 16 next week.
"There are no words to describe Messi, he always surprises you."
