York striker George Purcell has signed a two-year deal with Dover Athletic for an undisclosed fee.
City initially rejected the Whites' offer for Purcell, 23, before accepting an improved bid.
He told the club website: "[Whites manager] Martin Hayes is building a very good side here, one that can challenge for promotion.
"I just want to score goals. That's what I am all about. I'm confident of getting them here at Dover Athletic."
Hayes added: "York initally knocked us back but it seemed they were willing to let him go. We're delighted to get him.
"I don't think we're finished yet on recruiting. We're looking to get in another striker and a centre-half, then we're ready to go."
