Newcastle United are serious about securing Jack Harrison from Leeds United.

The 25-year-old went to Leeds from Manchester City a year ago, in a deal that included a 20 percent sell on clause.

According to The Mirror, Leeds value Harrison at £35 million, and there are suggestions Newcastle are willing to reach that price.

Part of the reason Leeds are asking for a high transfer fee is because of City's sell on clause.

Harrison is a key player in the Leeds side, and it is unclear if he is willing to move to Newcastle this summer.
