Afterwards, however, the 20-year-old was eager to highlight the role of his teammates on a memorable night in Bern.
Shelvey told liverpoolfc.com: "It's not just about me - it's about the team and we won 5-3.
"It was good to come back from 3-2 down and great to get the win. We just need to start off in the Premier League now.
"The boss has installed a lot of character in us. We've shown a lot of fight and belief so far this season to come back from goals [conceded], against Man City and again tonight.
"I've got to thank Jordan [Henderson] for my goals. It was great to score two goals and win the match."
