Jermain Defoe's winning goal in Sunderland's 2-1 victory over Leicester City was his 250th goal in English club football.
A Robert Huth own goal handed Sunderland a well-deserved lead, with Defoe doubling the lead from close range.
It was his eighth goal of the campaign so far and he says the win shows how much Sunderland have improved under manager David Moyes.
Defoe told BBC Sport: "Leicester are a great side, the champions, but our energy levels once again were good, setting the standard from the first minute.
"From the goalkeeper all the way through the side, everyone played their parts and did well, and it's three points.
"You're now seeing what our new lads and our manager can do.
"We're improving so much and it's exactly what the manager wants.
"We could have scored more, but at 2-1 we'll take that win against a good side."
