Joaquin talks Messi after full-time whistle

The veteran Betis midfielder played the full 90 minutes and was interviewed immediately after the game.

"When you're against Messi, who...who...*laughs*...well, we don't know what to say [about him] any more..." said Joaquin, as per the Guardian's Sid Lowe.

It's true - everyone is running out of superlatives to describe Messi. Gary Lineker agreed that he is just too good for words.

Joaquin was asked by El Pais to compare Messi and Ronaldo in 2017 - and there can't be many who would argue with his answer.

"Messi is the best player I've seen," said the 36-year-old Spaniard. "I've seen very good players, but this guy ... I got the feeling, on the pitch when I faced him, that he has the ability to win the game whenever he wants.

"I think he says this to himself: 'Now I will score', and he scores. And he's been doing it for 10 years. He's played 70 games during the year. He also changes the game when he wants, but as a finisher.

"As a soccer player in the literal sense of the word, I prefer Messi."

Barcelona are running away with the title, currently boasting an 11-point gap over their nearest rivals Atletico Madrid.
