Newcastle head coach Steve Bruce was stinging in his criticism of his side following their 5-0 defeat at Leicester, branding the performance at the King Power Stadium "a complete surrender".
The Foxes went ahead through Ricardo Pereira's 16th-minute opener but it was Isaac Hayden's dismissal shortly before half-time that was the catalyst for the Magpies capitulating after the interval.
Jamie Vardy scored twice, either side of Paul Dummett's unfortunate own goal, as the visitors conceded three times in the space of 11 second-half minutes before Wilfred Ndidi completed the rout late on.
The result left Newcastle second bottom in the Premier League, with only one win from their first seven fixtures, increasing the pressure on an exasperated Bruce.
He said: "It was simply nowhere near what's required. Ten men, nine men, the one thing you can show is a bit of resilience, a bit of determination, a bit of fight or a bit of courage.
"We haven't shown enough resilience and that's disappointing for me as I sit here because that's the only thing that I genuinely demand of them.
"We have to apply ourselves better than what I've just witnessed there because it was a complete surrender too quickly and too easily.
"I'm not going to single out individuals but the whole team performance, the whole lot of them were nowhere near what's required to go and make a fist of it in the Premier League."
