By contrast Bangladesh coach Jamie Siddons pulled no punches after watching his team concede 31 fours and a six on the opening day.
"We need to go back to the drawing board, bowl in good areas and be patient," the Australian said.
"Sending sides in is always difficult but we didn't put two balls in the same spot, our fast bowlers really let us down.
"It was overcast on a wicket that did look as though it would give us a little bit, but half an hour in the sun came out and the wicket didn't give us anything. With our attack we need a bit of help."
Bangladesh removed Alastair Cook for seven in the fifth over but saw Trott compile dominant century partnerships with Andrew Strauss and debutant Eoin Morgan.
"Our bowlers didn't capitalise on what was there in the wicket, we didn't swing the ball as much as we'd hoped," Siddons admitted.
"We let a lot of easy runs through and there wasn't any pressure. It's frustrating, the mistakes we make I would never see in the Australian cricket team, we're still making schoolboy errors on regular occasions.
"But we're getting there. We've got some really good players and I'm looking forward to the next few days to see if we can fight our way out of this.
"You need to get rid of those nerves and expectations of Lord's."
Bangladesh opener Imrul Kayes left the field after being struck by a full-blooded pull shot from Eoin Morgan when fielding at short-leg.
"He went straight for a scan but he's OK," Siddons said.
