"It's a great start for us," he told Sky Sports. "Not only because we got three points but we did so against a team who are one of the main contenders for the title and did really well in pre-season.
"It's a London derby too and in the last five years we have lost every game against them home and away, which makes it even bigger. It would be big anyway but this makes it a bit special.
"I know we have a good team, but I wasn't sure we were going to show that in the way we did, especially in the second half."
