Frank philosophical about the fine margins which counted in Brentford's first setback

Thomas Frank says Brentford have to learn how to seize key moments in tight games after suffering their first reverse in the Premier League.

Leandro Trossard's 90th minute strike for Brighton was enough to end the Bees' unbeaten start to life in the top flight.

"I think it was a completely even game between two sides that wanted to get on top," said the Dane.

"Until the 75th minute, I thought we were were better or at least had more dangerous situations.

"In the last 15, we were more under pressure. Defensively we set high standards, giving just four shots away. Offensively, in spells we were good but we need to be better. We had a few chances to score. We need to score on some of these chances."

Frank added: "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."

The story might have been different had Bryan Mbeumo taken one of three chances which came his way in the first half or if Ivan Toney's unexpected and spectacular crack from 35 yards drifted in under the bar.

"Ivan sees things that very few players are seeing," said Frank, who said there were positives to take from the display. "That would maybe have been goal of the year.

"Shannon Baptiste was very exciting to watch too. We just need to continue working now. We need to bounce back, it's all about that."
