Leeds United owner Andrea Radrizzani

Leeds United need to make up to three top signings in the summer transfer window to take them to the “next level”, according to Danny Mills.

Speaking exclusively to Football Insider, the former Whites and England defender praised Marcelo Bielsa for getting the “absolute maximum” out of his current squad but insisted new faces were needed to avoid “second season syndrome”.

This site revealed during the week Leeds are set to invest in top talent during the summer window despite last summer’s outlay leaving the Yorkshire giants with a wage bill in excess of £100million.

Leeds added Raphinha, Diego Llorente, Robin Koch and club-record signing Rodrigo Moreno during the summer window and have enjoyed a fine first half of the season.

“Realistically at the moment, it’s a Championship side,” Mills told Football Insider correspondent Connor Whitley.

“You’ve got to look at how Sheffield United have struggled with second season syndrome so you’ve got to add quality to the squad.

“What they did by bringing in Rodigo, Raphinha and Llorente when we see him play – that’s quality.

“You’ve got to add quality to get to that next level. If that means bringing in new players, that’s what you have to do.

“The way that Leeds play, they are effectively Championship players performing exceptionally well and putting in Premier League performances.

“If you want to go that next level you need quality and that means improving the players you’ve got which I’m not sure is doable anymore and I say that as a positive thing. From where they were, Bielsa has improved them to their absolute maximum and have done unbelievably well. They are absolutely outstanding in everything they’ve done.

“Now you just need to feed in, add two or three every season just to keep up the quality and keep refreshing it all the time.”
