City have now lost only one away game in the league - at Liverpool - of their last 21, and manager Pep Guardiola was delighted with them.
"This season will be unbelievable hard".
"So it wasn't going to be easy but it says a lot about the boys and where we're at".
"Sometimes it's hard to start the season but we started very well in pre-season, we won nearly every game".
"I thought Van Dijk was a good player at Southampton, but I didn't think he was worth £75m, and I didn't think he would have the impact on Liverpool's defence that he's had", Neville told the Gary Neville Podcast, via Sky Sports.More news: Tiger Woods fan dresses the part at Bellerive's PGA Championship

A revelation in his first season at Anfield with 44 goals in all competitions, Salah is now a marked man.
Finding the net is nothing new for Klopp on opening day.

The hosts finally doubled their lead to give the score the half-time reflection it deserved when another teasing Robertson cross was pulled across goal by James Milner and Mane left unmarked to side-foot home.
At the start of the second half Michail Antonio hooked over a corner but that was as good as it got for the visitors as Mane scored his second, benefiting from the absence of an offside flag as he converted Roberto Firmino's through-ball.
Former City and Real Madrid boss Manuel Pellegrini is used to competing at the top of the table.
"It's more competition, which is exactly what you want". We have started the season great and everybody is happy.More news: Google Pixel 3 XL live images, box accessories leaked
