The 20-year-old was scouted by the Premier League club at Molineux yesterday and caught the eye with a brillinat strike in Leeds’ 4-3 defeat.
John Rudge, the former Port Vale boss and a member of Hull’s scouting team, was sent by City to watch the game amid widespread interest in Leeds’ core of academy-produced players.
He is one of several United youngsters, along with Lewis Cook, Sam Byram and Charlie Taylor, who are likely to attract interest in the the summer transfer window after impressing at Elland Road this season.
United chairman Andrew Umbers told the BBC last week that the club were not willing to listen to bids for any of the four.
“Our young players are not for sale,” he said. “Contract negotiations are foremost in our mind.”
Cook and Byram have one season remaining on their deals while Taylor, like Mowatt, is tied down until 2017.
