He told the Mirror: "Winning at Liverpool, our biggest rivals, is always a fantastic result.
"But maybe it is even more important this time, because it is so close at the top of the Premier League this season.
"Ourselves and Arsenal have a great chance of winning the title this season because we are near the top of the league. But Chelsea and Liverpool are also playing well, so it's not just between us and Arsenal.
"But we have a good team, good spirit, and I believe we can do what we did last season and win the title again."
