The striker agreed that it was almost inevitable that he would put Wolves to the sword - as he has developed a habit of scoring against his former clubs.
Last season he scored home and away against Leeds, while in this campaign he has netted against Coventry and now Wolves.
"My job as a striker is to score goals - regardless of who it is against you want to score," he reflected afterwards. "I am delighted but I hope Wolves stay up as it is a team that is in my heart and all my family came to the game because of the Wolves connection.
"Like I said, it is nice to score goals and I hope Wolves do well and stay up."
Robbie reported that a half-time talk from David Pleat appeared to do the trick after Wolves made life tricky in the first period and the team responded with a four-goal second half salvo.
"We gave away a silly goal after scoring our first and needed to bounce back. David had a chat with us at half-time and it was important that we went out, starting playing and making chances for ourselves. That's what we did.
"It was a fantastic cross from Paul Konchesky for my second - he has a great left peg - and, luckily enough, I was in the right place at the right time.
"We said at the start of the week that it was important that we get two good results and we have."
Robbie Keane punished Wolves with a clinical hat-trick on Saturday and then expressed a longing for his first club to remain in the Premiership.
