Scarlets head coach Simon Easterby criticised his team after they were knocked out of the Heineken Cup courtesy of a 29-0 defeat to Clermont.
The French outfit rounded off a flawless Pool Five campaign by dismantling their hosts, who were in a generous mood defensively in a one-sided first half.
"We conceded 24 points in the first half and they did not have to work for a huge amount of those points," said Easterby.
"Any team where you conceded 24 points is going to be difficult, but a team like Clermont you dig a real big hole for yourself.
"It's frustrating. We just fed them too much in the first half. I think it was 70 per cent possession against and 70 per cent territory.
"We just need to be far more accurate. They scored off an intercept and fed off our mistakes. They are a quality outfit. We gave them too much of a headstart and gave them too much they didn't have to work for."
