Benitez said: "I'm pleased for Peter to get his two goals and he deserved them. The first goal is his. I was at a manager's meeting in Geneva recently with FIFA and we agreed that when a striker has a shot and it's deflected then it's the strikers goal.
"Everyone is delighted for Peter and the supporters showed him what they think of him. I hope he can now score more goals but as I said the most important thing is the team wins.
"We played very well against Wigan and we had three or four other clear opportunities to score. It's a pity we didn't score more and when you create the amount of chances we are then you need to score."
