Rantie, who was on loan at Bucs last season, stole the headlines when he scored three goals in extra time to help Malmo defeat Sandviken 6-3 in the Swedish Cup yesterday.
The Bafana Bafana striker is on loan to Malmo from another Swedish side, IFK Hassleholm.
Speaking to KickOff.com from Sweden this morning, Rantie says he will have to keep scoring.
"It was a great feeling to score three goals for my club yesterday," he says "I was happy to be on the scoresheet; that will only help boost my confidence.
"I'm very happy that I've been given the opportunity to play and I'm grateful for that ... I really want to thank my teammates for the support they gave me throughout the game.
"I'm glad that I repaid the coach's faith in me with a hat-trick – I will just have to continue doing that!"
The Free State-born striker also confesses that he misses Pirates, but says life goes on.
"I do miss Orlando Pirates and the club will always have a special place in my heart," he says.
"I would have loved to continue playing for them but things couldn't go according to my wishes.
"However, I am glad that now I am back in Sweden and I want to help my new team achieve success this season."
