Atletico Madrid coach Diego Simeone refused to discuss Antoine Griezmann going into Sunday's clash with Barcelona.
It's expected that the former Atletico forward will receive a harsh welcome from home supporters on his first visit back to the Estadio Wanda Metropolitano.
"Griezmann's history and numbers speak for themselves, I don't need to add anything," Simeone explained in his pre-match press conference.
"I won't talk about Griezmann because he plays for another team.
"What people do is their decision, I was always clear about what I thought of him when I worked with him."
