Messi stunned the Camp Nou when he passed his penalty into Suarez's path for the Uruguayan to complete a hat-trick in the Liga rout on Sunday.
The Argentina star could have converted himself to net a 300th league goal, but drew plenty of plaudits for his inspired display, which saw him open the scoring with a wonderful free-kick.

And Neymar opened up on Barca's preparation for the set-piece, revealing that Suarez was not the one who was supposed to score.
"We trained on this penalty routine, but for me. However, Suarez was near the ball and scored." he told reporters.
"We are really happy to be unbeaten in 30 matches. We are playing in our way and we want to keep this streak going."
Neymar completed the scoring as Barca regained a three-point lead at the top of the table with a game in hand on title rivals Atletico Madrid and Real Madrid.
