Porto striker Jackson Martinez insists he's not agreed anything with Atletico Madrid.
Atletico chief Miguel Angel Gil Marin has struck terms with Porto president Nuno Pinto da Costa over the Colombia international.
Atletico have agreed to match Martinez's €35 million buyout clause. They will also discuss sending players on-loan to Porto later in the summer, including Angel Correa and Oliver Torres.
For his part, however, Martinez insists: "I don't know if I'll play for Atletico Madrid.
“Atletico and Milan are two options. It's not only down to me. Everything will be clear next week."
