Sheffield United striker David Parkhouse has rejected the club’s offer of a new contract, Football Insider can reveal.

The club are trying to tie down the Northern Ireland Under-21 international to a deal replacing his current agreement, which expires next summer.

A United source has told Football Insider that Parkhouse, 20, has snubbed the offer to leave his future up in the air ahead of the January window.

That is a blow for the Premier League club, who have been impressed by the progress the centre-forward has made after taking his game to a new level this year.

He scored 19 goals in 39 appearances while on loan at League of Ireland side Derry City and was so successful the initial six-month deal was extended until the end of the League of Ireland season in October.

Scouts have been flocking to watch Parkhouse in action following his exploits, with Football Insider reporting interest from Celtic earlier this year.
