Speaking to TNT Sports, Elanga said: "It is all about the attitude from the lads. We wanted to start the game on the front foot and we did. Then we said let's keep going for more. We know how it felt last week and we wanted to make sure that Brighton felt the same.
"It is always nice to contribute. You could see I kept on running at the end because I wanted a goal. I said to Chris [Wood] at half time: 'Let's keep pushing for more.' I'm happy he got the hat-trick of goals. The most important thing is to win and we did that."
On pushing for Europe, he added: "It is all about taking it game by game. We can't be complacent. We have to keep working hard and continue to let our football do the talking and let the fans continue to believe."
