Crystal Palace winger Wilfried Zaha admitted he was stunned by his side's shock 2-1 victory at Premier League leaders Chelsea on Saturday.
Sam Allardyce's lowly team looked in for a long afternoon when they fell behind to Cesc Fabregas's fifth-minute strike at Stamford Bridge.
But Zaha produced a majestic display and the Ivory Coast international scored Palace's ninth-minute equaliser before setting up Christian Benteke's winner just two minutes later.
Zaha's heroics boosted Palace's chances of avoiding relegation and breathed new life into the title race, with Chelsea now just seven points clear of Tottenham.
"I'm stunned. They're top of the league. No one would expect us to come here and do that. I'm a happy man," Zaha said.
"We know there's talent here, we just needed to work together. Everyone is seeing it now.
"We didn't factor in this result but we had to believe in ourselves."
Chelsea manager Antonio Conte said his team, beaten for only the second time in 23 league games, had paid the price for defensive mistakes.
"We scored our goal after five minutes and then we conceded two in a few minutes. When you concede goals in that way you must understand the situation and improve on these mistakes," he groaned.
"This is football. We must accept this result."
Having watched his side's eight-match unbeaten run shattered by Zaha and company, Conte set his sights on an immediate response against Manchester City next week.
"In every game in England, anything can happen. The league is so strong. We faced a team today with strong players. I think they showed they were a good team," he added.
"Now we have to think about the next game. If we had won we would have been happy but now it's important to focus on Manchester City."
