The 23-year-old is in his second season on loan at Elland Road, and this campaign he has shown why Leeds were desperate to keep him for another year.
He boasts an impressive contribution of five goals and six assists this season, which has already bettered his tally of four goals and four assists from 2o18/19. Harrison has made himself a favourite among the Whites’ faithful, with his tireless work up and down the left flank.
Mills, speaking to Football Insider, said the asking price of £8million is “very viable indeed” and compared Harrison to his former teammate Jason Wilcox.
Mills said: “At the end of last season I think Manchester City wanted £15million for him, he is good but he has not got a pack of diamonds in his pocket.
“That was a little bit expensive for how well he had done. Now, the option at £8million is very viable indeed.
“He reminds me of Jason Wilcox. He is going to hug the touchline, get good crosses into the box and works his socks off. Very rarely lets you down. He is of that ilk. He is not the type of player that will get you 15 goals a season but what he gives you is width and work rate.
Harrion is an ever-present this season, in a Leeds team that find themselves second in the Championship, 10 games away from a long-awaited return to the top-flight.
