Wales Sevens coach Paul John was disappointed that his side were unable to hit top form against New Zealand in Moscow.
The 2009 World Cup champions defeated Fiji in their pool match but were unable to compete against New Zealand the following day, with the Kiwis eventually going on to win the title.
Having dropped out in the quarter-finals, John believes his team had endured a mixed tournament and lacked the self-belief that they could take down the World Series champions in their 26-10 defeat.
"The boys put in a huge performance yesterday against Fiji but we couldn't follow it up today against New Zealand," said John.
"We made too many basic errors so we are slightly disappointed in the manner of our exit in the tournament.
"We didn't reach the standards we played yesterday so it's disappointing to go out on that note.
"Looking back at the tournament, we have proved we are a very dangerous side. We let in a few tries against Tonga but beat Fiji, so we've had a few ups and downs but that's the nature of sevens.
"I just think we have to believe in ourselves a bit more when we come up against New Zealand in the future."
