And Wenger, whose team host Fulham this evening aiming for their sixth successive league win, said: "Robin is top, top, top in the world at the moment. Hopefully we can keep him going.
"He is enjoying a period where it is natural for him to score. When you are not desperate for goals, you score.
"I don't know if there is a better striker in the world at the moment. We have Messi, we have Ronaldo, we have many good strikers. I don't try to compare him with other strikers. I just want to keep him going as he does at the moment for us.
"We are reliant on Robin, of course. But I think we have enough cover if he gets injured or we rest him."
