The Whites narrowly missed out on promotion this season and Grayson thinks the sale of veteran defender Jansson could finance multiple signings.
“There are other players I would want to keep ahead of Pontus Jansson,” Grayson told Omnisport. “People like Kalvin Phillips and Jack Clarke, the younger players who can be the bedrock of Leeds for the next few years.
“I think Jansson does well when he concentrates on what he is there to do, in terms of being a defender
“Of course, they want to try and keep hold of them if possible, but players have been sold in the past to finance the next group of players.
“Roofe has proved he is goalscorer and Phillips, with his versatility and age, his ability on the ball, he is such a key player for what Leeds have done this season.
“I think he has a really bright future in front of him and let’s hope they can keep hold of him.”
