Bukayo Saka's stunning strike and a first international goal for Morgan Rogers inspired England in a 3-0 win over Wales, but Thomas Tuchel slammed "silent" fans at Thursday's friendly.
Tuchel's side delivered their second successive dominant display to maintain the feelgood factor after their 5-0 rout of Serbia in a World Cup qualifier last month.
Rogers put England ahead early in the first half at Wembley and the midfielder's Aston Villa team-mate Ollie Watkins increased their advantage soon afterwards.
With England carving open the hapless Welsh defence at will, Arsenal winger Saka scored the goal of the night with a superb long-range rocket.
It was exactly the kind of swaggering performance that former Bayern Munich and Chelsea boss Tuchel had promised when he replaced Gareth Southgate.
The German struggled through a spluttering start to his reign, but England are finally starting to hit their stride.
However, Tuchel felt England's display deserved a more vociferous response from fans as he took a swipe at the subdued Wembley crowd.
"We cannot do more than being 3-0 in a derby. I would have wished for a bit more support in phases where it gets difficult," he said.
"The stadium was silent. We didn't get any energy back from the stands. We did everything to win. If you hear just Wales fans for half an hour, it's sad because the team deserved more support today," he added.
"In the second half it could have helped us to regain energy, but it is what it is."
England's place at next year's World Cup is already all-but-confirmed after five successive wins in Group K.
They could book their spot with a victory in Latvia on Tuesday, depending on other results over the next few days. (AFP)
