Alastair Cook is confident England can build upon their impressive first-Test victory over South Africa at Kingsmead, highlighting the team's hunger as one of the greatest strengths.
The tourists overcame the world number one Test side with a 241-run victory on Wednesday, taking six wickets in 24 overs to see out the win on day five.
The captain believes England's showing in Durban displays the belief within the side and they will be heading into the second Test in Cape Town on Saturday full of confidence.
"Over the last eight months or so the guys have taken big strides forward as a side. Potentially, this team can do some really good things," Cook said.
"This a good side to captain; we feel balanced, the guys feel particularly happy and really hungry to push on.
"You see the guys training - from one to 17 in this squad - and think: 'There are good times ahead'. There are going to be some tough times, there always are, but it was a pleasing five days."
However, despite dispatching the Proteas so comfortably on the final day, Cook does not feel the tourists will suffer from over-confidence at Newlands.
"The danger is the word complacency, but that won't happen in our squad - that's not where we're at as a side," he added.
"Let's not get too carried away but it would be great if we can continue to push pressure on South Africa in the next game.
"This team are very talented to start with and hungry to do well. Playing for England means so much to the guys and it's such a fantastic thing to be able to do and say.
"The guys know what's out there for them if they're prepared to work hard."
