It became clear what disappointed L. Messi said to the referee.

The last round of "La Liga" ended in disappointment for both Lionel Messi and the entire Barcelona team.

The 30-year-old Argentine failed to break his goal drought, but at least one accurate shot had to be recorded in the match protocol.

In the first half, the ball crossed the Valencia goal line after a sniper's attempt, but the referee decided otherwise.

At half-time and after the break, microphones placed beside the field captured a conversation between L. Messi and the referee.

"You made a mistake, now you will see everything", the forward insisted, soon attacking the assistant as well.

"The situation was not clear, and I am not sure if the goal should have been counted", Ignacio Iglesias rejected the complaints.

Then Messi turned to Barcelona's goalkeeper coach Jose Ramon de la Fuente, asking him to confirm that he was right.

"The ball was here, and the line was here," Messi vividly explained.

The match ended in a 1-1 draw.
