Ilkay Gundogan has warned Manchester City that Liverpool will prove their sternest examination of the season this weekend.
Top-of-the-table City make the short trip to Merseyside to take on Jurgen Klopp's Liverpool on Sunday.
Both sides are on 19 points after their first seven matches of the season but City have only managed to avoid defeat on five of their last 17 visits to Anfield.
Gundogan told ESPN FC: "It's very tough, probably the toughest away game of the season in the Premier League.
"But as a player there is not much more that you can achieve than playing these type of games, because when you play them or when the atmosphere is like that, you know it's a big thing.
"So there's nothing better than playing these type of games.
"Although you're much more nervous before these type of games than in others maybe, even then after your first successful pass, first successful tackle or your first good dribble, you get more and more confidence."
