Samoa sevens captain Reupena Levasa admits their recent performances in the World Series have not been acceptable.
The Manu finished a lowly 14th in Wellington at the weekend, missing the Cup quarter finals for the third tournament running and winning just one game out of six.
After ending the tournament with a 26-10 defeat by Canada in the Shield final, Levasa says head coach Fuimaono Titimaea Tafua gave the team a dressing down.
"He feels very disappointed but at the end he still advises for some changes with us, especially our attitude and discipline, on the field and out of the field, so for us we have to work hard, especially next week's tournament in Vegas".
Reupena Levasa says there's always a big Samoan fan base in Las Vegas and it's good to be playing in a tournament where they've been successful, winning in 2010 and 2012.
However it won't get any easier, with the Manu Sevens drawn in a blockbuster
Pool A alongside Wellington champions New Zealand, Pacific rivals Fiji and former World Champions Wales.
All Blacks Sevens coach Sir Gordon Tietjens was shocked when he found out the other teams in their pool.
"Yeah you feel confident but sevens is a pretty fickle game sometimes. On a smaller field you look at the support that Samoa get there - they've won that tournament a couple of times - and Fiji, of course, they will be wanting to get back too and Wales are never easy so we can expect tough games".
Samoa slipped to ninth in the overall series standings following the Wellington tournament, while Fiji slipped to third after winning the Plate title.
South Africa remain on-top, ahead of New Zealand.
