He broke into the first-team last season, having impressed for the youth-team and won his move after scoring ten goals this season. However, the move is still subject to a medical.

The Hillians put him on contract last November and he had a trial at Millwall in the summer before playing for Oxford United Development last week before passing up on an offer to move there in favour of joining The Tigers.

Chairman Kevin Newell said: "We are all delighted that Greg has made his first step towards realising his ambition to play at the highest level – though our pleasure is tinged with the disappointment that we will no longer have Greg's talents at our disposal.

"He has been a key player for us this year and has been influential in the tremendous start to the season we have enjoyed. However, we have always made it clear to our younger players that we would help them progress their careers in any way possible and we are happy to honour that pledge with Greg."

Terms of the sale remain confidential, but Newell added: "I am sure that the terms agreed will stand the club in good stead for the promotion push that we are undertaking."
