In the last week he hit a double in the 3-0 win at Villarreal as well as heading the winner in the 3-2 thriller at QPR.
He said: "I came here because I wanted to make history. I want to be part of history at this club.
"For me it's the most important thing. We try not to think about going unbeaten, because the Premier League's not easy and other teams will try to beat us.
"It will be very difficult but we hope we'll continue unbeaten."
