Having lost the services of Harry Cardwell, who joined Southend United in January, Vermiglio swooped for Sampson last month.
The 28-year-old, who is enjoying his second spell at Victory Park, showed his worth with two excellent finishes and Vermiglio is thrilled with the way the striker has settled at the club.
He said: “I asked Jack when was the last time he scored two goals in a game?
“He said it was probably when he was last with us.
“You can see just be the way he plays that he is a great asset.
" He is used to playing with his back to goal and feeding players. We do have runners here at this club.
“I think his all-round game will evolve and develop to suit our system and the players that we have around him.”
This evening, Chorley are back on home territory when they welcome Spennymoor Town to Victory Park tonight, before Saturday’s visit of neighbours and play-off rivals Southport.
“It does not let up,” said Vermiglio. “We have a big game tonight.
" We will make sure we will get our minds and bodies right because games like the one against Chester do take it out of you.
“It’s going to be tough against a team like Spennymoor and then Southport who are right up there vying for play off position.
“We are in a good position at the moment with games in hand but those games in hand mean nothing unless you get points on the board.
"We have got 15 games left and we probably need another seven or eight wins to confirm our positions.
