Manchester United have been urged to avoid signing Leicester City ace James Maddison.
That's on the advice of former United midfielder Kleberson.
"I don't think it would be great for Maddison to join United," the World Cup winner told US-Bookies.com.
"They [Leicester] have had a good start to the season but when you do a big jump from a smaller club to United, it is mentally tough for these players.
"They have to be able to learn to adapt to play at a big club. It will be interesting to see if they can, but I don't know if he will be a good enough signing for United."
