The Whites weren’t at their fluent best on Saturday, yet they looked set to take a hard-earned draw back to London.
However, a lapse in clearing the ball allowed Lukas Nmecha to strike late, snatching all three points and leaving Silva disappointed.
“It was not a good performance at all,” he told the media.
“We lost the game, we have to congratulate Leeds, and we'll move on.
“Analysing deeper, the performance first half was balanced really, not any team on the front foot. We had our moments, they had as well, (but) not clearcut chances for any side.
“And second half, we didn't perform at the level that the game demands really. As simple as that. They scored in the end, but they had chances to score earlier than that.
“Of course, we are disappointed with the moment that we conceded the goal, and we should be, because in that moment we should defend much better. Three/four duels that we lost in a row there, that we should not.”
