Porto striker Jackson Martinez says he's relishing his move to Atletico Madrid.
The Colombian announced he would be joining Atletico last week.
“I'm going to approach it like I've approached every big challenge in my career.
"Hopefully I'll be as successful as he was. Atlético play a different system to Porto, but they're always fighting. They have achieved great things in recent years and have players that know each other well," he said.
