England took the lead through a 55th minute Anthony Gordon goal, but following several defensive substitutions from Tuchel, they played into Argentina’s hands.
Tuchel has faced heavy criticism for his approach to the game, with reports suggesting that even the players were ‘stunned’ by it.
Speaking to reporters after the game, Tuchel reaffirmed his commitment to the job and shifted the blame from his own tactics to English football's 'DNA’.
"In this moment my feeling was no structure in the world could have helped us," Tuchel said.
"Because actually we were too passive and we were not physical enough, we didn't stop runners arriving in our box and the deliveries were wrong too.
"I haven't seen the data yet, but I think just right after the goal the momentum swings completely and ball possession drops dramatically.
“We couldn't find any duels anymore; that's why we dropped deeper and deeper. It was never the plan, but it happened.
"(We) couldn't stop the runners from the second line, the midfielders, through our gaps, and the deliveries were on the highest level.
“You need to get back on the ball; otherwise you cannot break the pressure, and you cannot get the momentum back.
"I think ball possession plays a crucial role; it's maybe not in our DNA like it is in our Spanish DNA or in our Argentinian-Brazilian DNA, to take the ball and control the game with the ball."
