Georginio Wijnaldum believes teams should be worried about visiting 'fortress' Anfield after Liverpool clocked up another convincing home victory.

The Reds extended their unbeaten run in front of the Kop to 23 games on Tuesday as they came from behind to beat Stoke City 4-1 and move up to second in the Premier League.

Manchester City will hope to bring an end to that hot streak when they make the trip to Merseyside for a heavyweight clash on December 31.

But Wijnaldum says that will take some doing, as Jürgen Klopp's team take great confidence from playing in front of their own fans.

"I think Anfield is a fortress," he told the Liverpool Echo.

"The way we are playing and the way we are scoring goals in the home games, I think it will scare opponents.

"What I see right now is that we have a lot of confidence. We learn quickly and adapt to situations in games.

"We conceded the first goal against Stoke but from that moment we were still focused. We knew we could score goals.

"It's always good to win before a big game because you go into it with more confidence."

By hitting four against the Potters, Liverpool moved onto 45 goals scored in their first 18 league games of 2016-17 - six more than their nearest rivals, Manchester City and Arsenal.

Wijnaldum says he is not surprised by the feats of the best attacking team he has ever been part of, and expects the Reds' next game to be as full of goals as those that have preceded it.

"I played in a team at PSV who also played with a lot of attacking players but this is the Premier League and this team is better," he added.

"Forty-five league goals is a lot but we have a lot of players who can score goals and win games for us.

"That's a good thing because if it depends on one person, it can be a problem because if that person doesn't score, you will not win games.

"City also have a good attack and good players on the bench who can come on and score goals.

"I don't think there is a big difference between the teams. We have to play with the players we have and I'm happy with that because we have a great squad.

"It's two teams that want to attack and score goals so it's going to be an interesting game.

"It's not only Aguero, you also have to stop [Kevin] De Bruyne, [David] Silva, [Raheem] Sterling... you can go on."

The Reds remain the closest challengers to Premier League leaders Chelsea, sitting just six points behind in second.

But Gini isn't focusing on what Antonio Conte's men are doing, preferring to put all his concentration on helping Liverpool maintain their own good run.

"The season is long. You can't control other things and other games will come after Manchester City," he insisted.

"Chelsea might come into a bad situation and drop points. They may not, you never know. We have to keep going."
