Nigel de Jong has declared his Manchester City side must keep up the standard from Monday's victory against Liverpool to mount a Premier League title challenge.
The Blues claimed an impressive 3-0 victory after an early strike from Gareth Barry and a brace from Carlos Tevez. After another summer of huge spending, the result went some way to showing the cash could be turned into trophies.
Speaking to the club's official website, De Jong urged his colleagues not to rest on their laurels.
He said: "As a midfield, I thought we played well as a unit.
"James Milner had a fine debut, Gareth Barry scored a good goal, and Yaya [Toure] and I did what we do.
"I think anyone would agree we have enough quality in our whole team to be challenging. Now what we have to show is that we have the mentality too.
"We want to win this league - that's the ambition - but to do that we have to hit these standards every week."
Despite being a first team regular for both Manchester City and the Netherlands, De Jong is rated as just the 534th best player in the top five leagues in Europe in the Castrol Rankings’ study of European football.
