Jarvis insists West Ham have what it takes to spring a surprise result against Manchester City.
"It's a massive challenge but I think people didn't expect us to beat Tottenham either," said the winger.
"We need to concentrate on the Premier League for the time being. This result is a massive confidence booster. We needed a win and to get it at Spurs is a massive thing."
