The Swedish winger made his debut for the club last week in a home defeat to Leicester City before putting the Reds ahead early on with a powerful header at Molineux.
Speaking to MUTV's Stewart Gardener post-match, Elanga admitted he was flying high after his first senior goal.
“My debut's still not sunk in yet,” Elanga said with a smile.
“The fact I've scored today, that's still not sunk in yet either! It's just an amazing feeling, starting in the Premier League for the club that I've supported since I was young. I'm just so happy.
