Pique: Barcelona have my number, they can call if they want to discuss Griezmann film FIFA World Cup 2018 Griezmann debacle has continued to embarrass Los Cules

Spain remain unbeaten at the 2018 World Cup, yet back in Catalonia the fallout from Antoine Griezmann's documentary continues and Gerard Pique has responded to the news that Barcelona are unhappy with him.

Kosmos-Studios produced the French forward's dramatic documentary which detailed him agonizing over a move to the Camp Nou, however this company is owned by the Spanish defender.

"Barcelona have my number, they can call me if they want to speak," he explained in the mixed zone on Wednesday.

Pique was at the heart of La Roja's defence as the national team earned a 1-0 victory over Iran in Kazan, but it was not a comfortable match.

"They are doing a very good job," he admitted. "They have a culture of defending all the way to their goal, they play with spirit and soul.

"It's very difficult to score a goal, after [Diego] Costa scored they pushed up and caused us more problems."

The clash with Iran marked the former Manchester United defender's 100th cap for the national team, a milestone which has filled Pique with pride.

"I'm very happy," he confirmed. "The national team has been a very important part of my career.

"It's been more than 15 years since I made my debut for the younger teams."
