Leeds United owner Andrea Radrizzani

Leeds United winger Jack Harrison’s value is only going up after his impressive start to life in the Premier League.

That is according to former Whites full-back Danny Mills who, speaking exclusively to Football Insider correspondent Connor Whitley, suggested Leeds already have a deal in place to sign the winger permanently next summer that could save them millions.

Harrison, 24, is currently enjoying his third season on loan at Elland Road from four-time Premier League champions Manchester City and recently played his 103rd game for the club.

When his third loan move was announced in the summer Sky Sports reported the deal could be made permanent in 2021.

Mills insisted, with loan fees accounted for, a deal next summer would be great business for the Yorkshire giants.

He told Football Insider: “It’s bizarre, isn’t it. He’s got to be one of the longest players on loan at a single club ever. Over 100 appearances – it’s unbelievable.

“I’m assuming Leeds are paying a loan fee every season. Leeds are giving him game time and Man City are clearly not bothered. They don’t want him in their squad.

“You start to think ‘hang on a minute, we’ve paid whatever it is £2million, £3million, £5million loan fee, surely they’ve got to start knocking that off the transfer fee is if there is one.’

“That transfer fee has only gone up because of what Leeds have done with him.

“Unless there’s been a deal already done behind-the-scenes that is there if both clubs want it to happen.

“If I had been Leeds I’d have said ‘we want to take him on loan but if we want to make it permanent this is what we’re going to pay and this is what you’ve got to let him out for.’

“I wouldn’t be surprised if there was something like that written in.”
