Andy Robertson thinks Liverpool were made to look “foolish” during their 3-0 loss to Napoli in a pre-season friendly on Sunday.
Lorenzo Insigne, Arkadiusz Milik and Amin Younes bagged the goals as the Serie A side went on to secure an impressive victory.
The loss means the Reds are now winless in their last four friendlies, losing to Sevilla and Borussia Dortmund and drawing with Sporting Lisbon.
“And we need to look at it and improve as our season starts in a week and it doesn’t get any harder than Man City.
“We need to be a hell of a lot better than this.
“Jordan Henderson and James Milner pulled us in for a huddle on the pitch and what was said cannot be repeated until after 9pm. It’s not crisis meetings, it’s pre-season.
“But we can’t get into a habit of losing or drawing. We need to step it up massively.”
Gini Wijnaldum added: “Today we were not 100 per cent concentrated. We didn’t play as a team and made too many mistakes.
“It’s important to keep confident and keep going. It’s painful but we have to learn and strike back.”
