I can’t understand what he says here. He MIGHT be saying “He’s like greased lightning”. This is an old idiom that means “very fast”. I don’t know the origin of this idiom. I haven’t heard this in a very long time.
Similar sayings are “lightning fast” and “fast as lightning”.
He means “go on and try to score a goal”. When he says it twice like this, it means that the speaker (P.S.) doesn’t think that Chips can score a goal. So he wants to Chips to try it to prove that P.S. can stop Chips. Then Chips scored the goal anyway, so P.S. wasn’t as good as he thought.
