Newcastle United players had previously experienced an unhappy Matthias Jaissle in training, but the head coach was especially forthright after a 4-1 defeat at Elland Road. "There was all clarity in the room that the learning curve needs to be really fast," Jaissle said. Even during a five-game unbeaten run, there was recognition this was "always going to be a work in progress" after huge summer change. Newcastle went from one of the most experienced Premier League line-ups last season to the second-youngest.

The manner of the first loss still jolted. Much will be learned from how Jaissle's team respond against in-form Hull City on Saturday. "If you're tougher in the duels, more aggressive, sharper and hungry to collect second balls, then it will automatically be a huge step," he said. Jaissle was parachuted in three weeks before the season after Eddie Howe stepped down.

Injuries to Dan Burn, Joelinton, Anthony Elanga and William Osula have hardly helped. No team have faced more shots (76), while Newcastle average little more than three on target per game. They struggled against an aggressive Leeds side, even before Nico Gonzalez went off with concussion in the 19th minute.

Vertical football is Jaissle's trademark, but too often Newcastle punted forward for Yoane Wissa and Matias Fernandez-Pardo. Leeds' three centre-backs outnumbered the pair and Newcastle were swarmed in midfield. Meek Newcastle lost 56% of first-half duels and defenders Malick Thiaw and Sven Botman were bullied by Dominic Calvert-Lewin, who scored twice.

A warning came when Newcastle failed to match Bournemouth's intensity and were 2-0 down after 35 minutes. Jaissle stressed his "fundamentals" were "non-negotiable" and how players needed to take losing a duel personally. He spent the bus journey home digging into the detail.

However, just as he has not got too high after positive results, he has not emotionally ripped up foundations after a setback, as Zlatko Junuzovic explained. "They analysed the situation and, where necessary, made one or two adjustments, but nothing drastic," he said of their time in Austria.
