"I am delighted - not only with the win, but the style," Allardyce said.
"It has been coming for a while, but our lack of finishing has cost us. What we saw today is what we have been missing. The quality of our goals and our football brought us a fantastic result. We were desperate for it.
"We started really well, we pressed and didn't sit back. I had three weeks to think about this game and sort the tactics. We said, 'Let's go, let's go challenge them' and it worked extremely well."
