Villa won 2-1 at Spurs on Sunday to further consolidate their current form revival.
“It was a massive win,” Cash told Villa's website. “It’s a really tough place to come.”
“Before the game, we were speaking about how we’ve been here and won before, so we know what it takes.
“I think we were resilient all around the pitch, and then Emi comes on and scores the winner.
“It was a nice pass! It paid off. We work on set pieces and second phases and always try and hit the furthest man.
“It was a nice contact, and a great win.”
Cash added: “We had a tough start to the season, I think everyone knows that, for different circumstances.
“But all you can do in them times is work hard and try to do what we’ve been doing over the last few years – be resilient, score on the counter.
“We’ve picked up some great results, that’s five in a row now, so a really good win and hopefully we can keep the momentum.”
