It was in stark contrast to Saints head coach Tonda Eckert's near-10-minute address, and summed up the overall mood at London Stadium.
Only two reporters asked the former Wolves, Spurs and Nottingham Forest man any questions, with one on the injury of absent defender Joel Veltman.
Espirito Santo, whose Hammers missed the opportunity to go top of the Championship table, admitted he was disappointed they did not score more.
"Our reaction in the defining moments meant we conceded three goals, and this made our job really hard. In the second half, we tried," he said.
"We started the game not the way we wanted, and we conceded, and we were punished, but we had more than 50 touches in the Southampton box.
"This is a lot of volume in our offensive game, but we have to credit their goalkeeper [Daniel Peretz]. He did a fantastic job today. A fantastic job."
The two sides do not have to wait long to do battle again, with Saints hosting West Ham later this year, on Tuesday, December 29 (8.15pm kick-off).
