Fulham boss Marco Silva admitted frustration after their 2-2 draw with Burnley.
The Cottagers gave up an injury-time equaliser scored by David Datro Fofana to share the points.
Silva said: "It's a really difficult one to take. Not the first time this has happened. Overall our performance in 2-1 was at a very good level, everyone felt another goal was coming for us.
"The first goal we conceded gave them a boost, the crowd as well. As a team we were naive in that moment, and were punished.
"We were fresh enough on the pitch, it is just we don't keep focus and are naive in some moments. These are details that will punish us hard this season."
On Rodrigo Muniz, who scored his first Premier League goal, Silva added: "A very good performance from him. A very good first half, good moments in the second half too. He's a young boy who works very hard."
