Brighton boss Roberto de Zerbi played down a row with rival Thomas Frank during defeat to Brentford.
The Seagulls lost 2-0 on Friday night.
De Zerbi said: "I think to win the game you have to score. We had 21 shots on the goal but we have not found the goals. We lost the second ball too many times.
"About the game I think we played a good game but if you want to win you have to score. I can't say anything more.
"We have had a lot of potential chances but many shots on the goal and we didn't find the goal. The time, the last pass, the crosses, we made mistakes."
On the importance of Brentford's penalty, he also said: "It was a crucial moment but I had belief until the end of the game because one goal could have opened the game again."
On his clash with Frank, De Zerbi added: "No problem [between us]. I don't like when the other coach touches my player and when another coach speaks with my player because I never spoke with the other player from the other team."
