Mauricio Taricco gave us the advantage three minutes after the break following a positive first half display, but Michael Owen replied just two minutes later and Liverpool seized the initiative.
Gus reasons that after scoring the goal, the team should have opted for extra solidity and not immediately set about adding to the scoreline.
"It was the kind of game where you know you've got to be kind of 'safe' - clever at the back, not risk too much," reflected Gus. "Normally the scoring of one goal will win the game.
"I think the goal by Tano - his first time - unfortunately changed the game. After that we made mistakes and were punished. Then it was all uphill and difficult to come back.
"We were all over the place and were maybe too open. I am not talking about the third goal, but the first two - that's football.
"In that type of game, if you keep on trying you are going to get something - like we did with Tano. The problem is after that, to finish the game you have to be really clever about the result.
"The reply was too quick. After that we should have quietened the game down and said 'okay, let's get back to basics as it is still 1-1'. We were trying to get back the lead as soon as possible."
Gus Poyet feels the team responded in the wrong way after taking the lead against Liverpool on Sunday.
