Diego Maradona has taken aim at Argentina coach Jorge Sampaoli.
Maradona is upset with the former Sevilla manager, claiming he betrayed him.
"He arrives at the national team with an arsenal of assistants and wants to explain that the ball is round," Maradona explained to CNN.
"It seems to me that that is where he is most wrong. Those of us who are from football don't remember seeing a goal scored by Sampaoli, or hearing about a goal by Sampaoli.
"So he has to have great respect for what we left, for what we did with the Argentine national side.
"Sampaoli betrayed me.
"When Argentina won the Davis Cup, he told me that he wanted to pay tribute to me in Seville and I said I wanted to talk about football afterwards.
"I said yes, but you see that the man already had another thought and would have thrown waves elsewhere.
"He didn't want to talk to me; he wanted to get closer to the national team."
