Tuchel said he used his first two England camps to learn, but from now on in camps three, four and five it would be about increasing competition, then narrowing down his squad.
So no wonder England’s head coach was beaming broadly as he departed his media briefing after the most satisfying display since he succeeded Gareth Southgate.
England became the first side to score five goals in an away competitive match against Serbia.
And they have now won eight competitive games in succession, goalkeeper Jordan Pickford keeping his seventh consecutive clean sheet.
England stifled Serbia and the hosts failed to get any of their three shots on target, leaving Pickford without a save to make.
England had 24 shots and 12 on target while they had 42 touches in the opposition box as Serbia recorded just four.
Madueke and defensive pair Ezri Konsa and Marc Guehi all scored their first England goals on a landmark night.
The good news arrived in bundles for England and Tuchel.
Tuchel could almost gorge himself on the food for thought this game offered him.
England were warned the atmospheric Rajko Mitic Stadium would be hostile territory, with the players making the 240-metre walk down the arena’s famous tunnel.
Instead, England silenced Serbia’s fans from the start, dominating possession, giving those expectant supporters no chance to turn up the volume.
There were some unsavoury incidents.
The game was stopped in the first half when green lasers were shone at Konsa, while there was an outbreak of fighting among the home fans in the second half, with some supporters protesting against Serbian president Aleksandar Vucic.
Serbia and their feverish supporters were beaten from the moment captain Harry Kane put England ahead, the all-time record goalscorer showing there are still no serious contenders for his place with his 74th goal in 109 internationals, a remarkable record.
No such problems for Tuchel and England, who delivered the sort of dazzling performance and statement victory their supporters have been waiting for since his appointment.
