Shelvey enjoyed an impressive performance at Anfield.
"I'm delighted to score my first Premier League goal, especially at Anfield," he told Liverpoolfc.tv.
"It was a great performance from the team and we started off really well. If we'd been able to do that on Saturday, it may have been a different story and we'd have the FA Cup as well.
"I saw the 'keeper mis-kick and the ball fell on my right foot. I heard the crowd shouting 'shoot', so I thought, 'Why not?'
"It came off sweetly and went into the back of the net."
