West Ham United winger Matthew Jarvis admits his team need to improve after Saturday's defeat at home to Stoke City.
"I was very disappointed with the performance and the result, really, especially with it being at home where we have such a good record," he said.
Jermaine Pennant scored an 82nd-minute winner, curling the ball around the West Ham wall with a sumptuous free-kick. It was only the Irons' second home defeat in 2013.
Jarvis, who wasn't included in Roy Hodgson's World Cup qualifiers squad for Friday's visit of Moldova, feels frustrated that the Hammers were unusually poor against Mark Hughes side.
"Stoke did play well but we didn't play our usual high-tempo game, especially at home where we're normally very good," he added.
The team from the Potteries were more dangerous at the weekend, winning the possession battle and having more shots than the home side. Jarvis is adamant that they will overcome the performance and turn things around when the fixtures resume.
"We're going to have to sort it out and make sure it never happens again and get back to winning ways and what we normally do at home," said the former Wolverhampton Wanderers man.
Sam Allardyce's side travel to St Mary's to face Mauricio Pochettino's Southampton on September 15 in their next Premier League game.
