Brentford boss Thomas Frank says they must learn from their late defeat to Brighton.
Leandro Trossard struck a 90th minute winner for the visitors.
Frank later said: "It was an even game between two sides that wanted to get on top. Until the 75th minute, we were better or at least had more dangerous situations.
"In the last 15, we were more under pressure. Defensively we set high standards. Just four shots away. Offensively, in spells we were good but we need to be better. We had chances to score and we need to score some.
"One moment decides the game and that is the Premier League. A solid performance. We could have edged it.
"We need to look into the performance. We played a good Brighton side and were unlucky."
