The England U21 international faced his former employers on Monday for the first time since completing a summer switch to Swansea City.
He was to be the star of the show at the Liberty Stadium, but not always for the right reasons.
Shelvey opened the scoring in a 2-2 draw, and laid on Michu's second-half leveller, but saw two sloppy passes punished by Daniel Sturridge and Victor Moses as Liverpool threatened to steal the points.
The promising midfielder apologised to Swans supporters afterwards, but those who play alongside him feel he should be looking to take positives from an evening of mixed emotions.
Dyer told Sky Sports: "He's 21 years old. His strength of character is amazing. He is obviously a bit down, like anybody else would be, but he turned it around, set up a goal and his display towards the end was strong."
Dutch goalkeeper Vorm added: "He's a good professional and he knows what he did wrong, and that's why it's good that he played a good second half and had an assist to make it 2-2.
"He has to learn from it also. This is a game he won't forget for all his life, but you see that if you make mistakes against teams like this, they punish you. This time it was him, unlucky, but I think he played well.
"We win together and we lose together, so we aren't going to blame him. Next time it might be someone else. You just have to learn from it and, in the end, a draw was good."
Wales international full-back Davies is also backing Shelvey to bounce back, saying: "All the players are going to get behind him, but you can't overdo it or the pressure will sink on him.
"He knows himself that he made two mistakes, but nobody is going to get on his back.
"He's a strong enough player to show what he can do, and in the second half I think he showed how good he was and helped the team."
